"Learned" Facts Don't Populate in Add Potential Link Modal

[deacon-mp]

Describe the bug
In Caldera v5, "learned" facts (facts parsed by abilities earlier in the operation) do not appear in the Add Potential Link modal for selection.

To Reproduce
Steps to reproduce the behavior (using Caldera v5 on Linux):

1. Create a new operation using basic fact source.
2. Execute the "Find local users" ability. Note in the output that the parser has identified several host.user.name fact values.
3. In the "Add Potential Link" modal, select the "Find user processes" ability.
4. Note that the ability requires a host.user.name value, but none of the values learned in the previous step populate as options in the form.

Expected behavior
When navigating the "Add Potential Link" form, both "Learned" and "Imported" values of required facts should appear as options with a checkbox. This is the behavior in Caldera v4.2.

Tested On:

• OS: Linux (Ubuntu 22.04)
• Browser: Firefox
• Version: 5.0.0

Additional context
I assume in the Magma version of the Operation page, the fact source is only queried once when the operation is first created. Therefore, facts "learned" during the operation are never pulled and don't appear as options in the "Add Potential Link" modal. I intend to investigate when I have time.

I can see the confusion but learned facts are all displayed below the textbox with checkbox. Selecting the user you want to find the user process on does work using found fact "host.user.name". Since each system is different there may be multiple users found. Auto populating that field with previous found fact "host.user.name" is not required. Is it the intended action when manually adding links? Am I catching this issue after it has been fixed?
