Reproduction steps:

1. Create a new project
2. Create and open a new UI Document. Create → UI Toolkit → UI Document
3. Add a VisualElement to the Hierarchy
4. For VisualElement, expand headers for settings inside UI Inspector enough so that a scrollbar appears (the more headers expanded the better)
5. Dock the UI Builder anywhere in the Editor
6. Double-click on the UI Builder tab to maximise it
7. Scroll the UI Builder’s Inspector
8. Observe the result

Expected result: All fields and buttons are visible in the UI Builder’s Inspector
Actual result: Some fields and buttons become corrupted and are invisible
