Add collapse state store and provider apps/meteor/client/lib/constants.ts, apps/meteor/client/views/room/MessageList/contexts/*, apps/meteor/client/views/room/providers/CollapsedAttachmentsProvider.tsx, apps/meteor/client/views/room/MessageList/MessageList.tsx |
A bounded external store, React hooks, and provider persist attachment toggles around the virtualized message list. |
Scope and apply attachment collapse state apps/meteor/client/components/message/content/Attachments.tsx, apps/meteor/client/components/message/content/attachments/*, apps/meteor/client/views/room/MessageList/hooks/useKeepMountedMessages.ts |
Attachment paths scope collapse keys across messages and nested quote attachments. Keyed attachments use persisted state. Unkeyed attachments use local state. |
Validate persistence and isolation apps/meteor/client/components/message/content/attachments/*.spec.tsx, apps/meteor/client/views/room/MessageList/contexts/*.spec.tsx, .changeset/yellow-rooms-tease.md |
Tests cover persistence, isolation, toggling, bounded storage, and local fallback behavior. A patch changeset records the fix. |
Estimated code review effort: 3 (Moderate) | ~20 minutes
Merge Risk: 🟡 Moderate · up to 9d8f0
The PR preserves attachment collapse choices across message-list scrolling while keeping attachments independently keyed and supporting local fallback behavior. The current head is not merge-ready because a formatting failure blocks Code Lint and new implementation comments still violate repository coding guidelines; both should be corrected before merge.

Timestamp: 2026-05-06T20:48:08.244Z
Learning: In the RocketChat/Rocket.Chat repository, Meteor's bundler does not respect the `exports` keyword in `package.json` files. Deep imports (e.g., `rocket.chat/apps/dist/server/bridges/UiInteractionBridge`) must be used instead of relying on `exports` subpath mappings. Do not suggest adding `exports` map entries to packages consumed by Meteor (e.g., `packages/apps/package.json`) as a fix for deep imports.

Learning: In `apps/meteor/app/apps/server/converters/codecs/uploads.ts`, upload `path` is no longer persisted in the Rocket.Chat database. It is generated only when sending upload data to Apps for backward compatibility, so Apps-to-Rocket.Chat encoding must not restore or persist `path`.

Learning: Rocket.Chat repo context: When a workspace manifest on develop already pins a dependency version (e.g., packages/web-ui-registration → "rocket.chat/ui-contexts": "27.0.1"), a lockfile change in a feature PR that upgrades only that dependency’s resolution is considered a manifest-driven sync and can be kept, preferably as a small "chore: sync yarn.lock with manifests" commit.

Learning: In RocketChat/Rocket.Chat, the `push.token` POST/DELETE endpoints in `apps/meteor/app/api/server/v1/push.ts` were already migrated to the chained router API pattern on `develop` prior to PR `#39625`. `cleanTokenResult` (which strips `authToken` and returns `PushTokenResult`) and `isPushTokenPOSTProps`/`isPushTokenDELETEProps` validators already exist on `develop`. PR `#39625` only migrates `push.get` and `push.info` to the chained pattern. Do not flag `cleanTokenResult` or `PushTokenResult` as newly introduced behavior-breaking changes when reviewing this PR.

Learning: In Rocket.Chat’s native emoji rendering flow, ASCII emoticons inside `<code>` and `<pre>` may be converted into emoji spans by `apps/meteor/app/emoji-native/lib/getEmojiConfig.ts`, then restored to their literal `title` text by the downstream `apps/meteor/app/emoji/client/emojiParser.ts` DOM pass when the emoji span’s parent is `CODE`. This behavior is intentionally retained for parity with the legacy emojione renderer; structural HTML protection is planned as a post-release migration to message-parser/gazzodown.

In reviews, ensure the changeset clearly states: this is a non-breaking change, the major version should not be bumped, and the changeset reflects a minor version bump.

The out-of-bounds index is clamped by Virtua to `itemCount - 1` (last item) — this is intentional and relies on documented stable behavior of the Virtua library. Do not flag this as a bug.

Absence of `ignored` in a `subscriptions-changed` event means the user's ignore list is empty/reset, so clearing all existing `ignored` flags on messages for that room is the correct behavior. Do not flag this as an unintentional ignored-state reset on unrelated subscription updates.

Learning: In Rocket.Chat's Meteor client code, DDP streams use EJSON and Date fields arrive as Date objects; do not manually construct new Date() in stream handlers (for example, in sdk.stream()). Only REST API responses return plain JSON where dates are strings, so implement explicit conversion there if needed. Apply this guidance to all TypeScript files under apps/meteor/client to ensure consistent date handling in DDP streams and REST responses.

Learning: In Playwright end-to-end tests (e.g., under apps/meteor/tests/e2e/...), prefer locating elements by translated text (getByText) and ARIA roles (getByRole) over data-qa attributes. If translation values change, update the corresponding test locators accordingly. Never use data-qa locators.

Learning: For changes related to OpenAPI migrations in Rocket.Chat/OpenAPI, when removing endpoint types and validators from rocket.chat/rest-typings (e.g., UserRegisterParamsPOST, /v1/users.register) document this as a minor changeset (not breaking) per RocketChat/Rocket.Chat-Open-API#150 Rule 7. Note that the endpoint type is re-exposed via a module augmentation .d.ts in the consuming package (e.g., packages/web-ui-registration/src/users-register.d.ts). In reviews, ensure the changeset clearly states: this is a non-breaking change, the major version should not be bumped, and the changeset reflects a minor version bump. Do not treat this as a breaking change during OpenAPI migrations.

Learning: In Rocket.Chat, there are two different `ModalBackdrop` components with different prop APIs. During review, confirm the import source: (1) `rocket.chat/fuselage` `ModalBackdrop` uses `ModalBackdropProps` based on `BoxProps` (so it supports `onClick` and other Box/DOM props) and does not have an `onDismiss` prop; (2) `rocket.chat/ui-client` `ModalBackdrop` uses a narrower props interface like `{ children?: ReactNode; onDismiss?: () => void }` and handles Escape keypress and outside mouse-up, and it does not forward arbitrary DOM props such as `onClick`. Flag mismatched props (e.g., `onDismiss` passed to the fuselage component or `onClick` passed to the ui-client component) and ensure the usage matches the correct component being imported.

Learning: Field wrappers in rocket.chat/fuselage-forms (Field, FieldLabel, FieldRow, FieldError, FieldHint) auto-create htmlFor/id associations, aria-describedby, and role="alert" for errors. Do not manually set htmlFor, id, aria-describedby, or role attributes when using these wrappers. This automatic wiring does not apply to plain rocket.chat/fuselage components, which require explicit ID wiring per the accessibility docs. In code reviews, prefer using fuselage-forms wrappers for form fields and verify there is no unnecessary manual ID/aria wiring in files that use these wrappers. If a component uses plain fuselage components, ensure proper id wiring as per docs.

Learning: In tests (especially those using testing-library/dom/jsdom) for Rocket.Chat components, the HTML <code> element has an implicit ARIA role of 'code'. Therefore, screen.getByRole('code') or screen.findByRole('code') will locate <code> elements even without a role attribute. Do not flag findByRole('code') as invalid in reviews; prefer using the implicit role instead of adding role="code" unless necessary for accessibility.

Learning: In Rocket.Chat's Meteor client code, DDP streams use EJSON and Date fields arrive as Date objects; do not manually construct new Date() in stream handlers (for example, in sdk.stream()). Only REST API responses return plain JSON where dates are strings, so implement explicit conversion there if needed. Apply this guidance to all TypeScript files under apps/meteor/client to ensure consistent date handling in DDP streams and REST responses.

Learning: In Rocket.Chat’s Meteor client code, when calling `dispatchToastMessage` with `{ type: 'error' }`, pass the raw caught error object as `message` without manual normalization. `dispatchToastMessage` is designed to accept `message: unknown` for error toasts, so avoid converting errors to strings (e.g., `String(error)`) or extracting `error.message` before passing them.

Can you take a look at MessageCollapsible? There are other kinds of collapsibles I think we're missing, we just need to update the component to pass the key to useCollapse
Everything is covered correctly! MessageCollapsible is used by files and they are kept in the DOM. |
