InDesign 20.2 x64 on Windows 11

Steps to reproduce:
- Open any UXP based plugin panel on Windows OS (does not occur on Mac)
- Click inside the panel to "focus" it
- Press Alt+F4

Expected result:
- InDesign window/app is closed (Alt+F4 is the default Windows shortcut for closing a window)

Actual result:
- Plugin panel contents becomes blank.
- Situation is unrecoverable in InDesign. Closing the panel and reopening it has no effect. InDesign restart is required.

"Ironically" this issue also occurs for the built-in "Plugins" panel (likely also UXP based?)
