Cycle layout popup appears on primary monitor only

[chrisjbillington]

Describe the bug

The cycle layout popup, triggered by keyboard shortcut, is displayed on the primary monitor, even when the focused window is on a secondary monitor such that the layout change applies to that secondary monitor

To Reproduce
Steps to reproduce the behavior:

1. Set a keybinding for "Cycle layouts" in Tiling Shell settings
2. Focus a window on a secondary monitor
3. Use keybinding to cycle layouts
4. Observe the "Cycle layouts" popup appearing on the primary monitor, although the layout change does indeed apply to the secondary monitor.
