How to reproduce:
1. Open the “IssueUIBuilder.zip” project
2. Open the “UIDocument.uxml” file
3. Maximize, then un-maximize the UI Builder window
4. Observe the UIBuilder window

Expected result: The panel and UI Builder window are fully functional
Actual result: The whole panel is black

Reproducible in: 6000.0.52f1, 6000.1.10f1, 6000.2.0b2, 6000.2.0b8
Not reproducible in: 6000.3.0a1
Fixed in: 6000.3.0a1
Could not test in: 2022.1.0a1, 2022.3.64f1, 2023.2.0a23 (Not able to bind localization strings)

Reproduced on: Windows 11 Pro (24H2)
Not reproduced on: No other environment tested

Notes:
- Reproduces when the string is bound to other UI Builder fields, too
- After reproduction, other tabs can be opened by clicking where the tab headers should be. Then, selecting the UI Builder tab will freeze that panel again
- If the UI Builder is opened through the UXML file, the UI Builder will render correctly
