Thank you for reporting a bug to Unity. After reviewing the behavior, we've confirmed it aligns with the current design and intended use of the feature. We understand this may differ from your expectations or workflow. We will close this case as 'As Designed.' If you have feedback on how the feature could better meet your needs, please let us know - we value your input and consider it in future improvements.

How to reproduce:
1. Open the attached project “IN-135458”
2. In the Project window, open the “Assets/UI Toolkit/UIDoc” asset
3. In the UI Builder hierarchy, select “NegativeCircleElement”
4. Press ‘F2’ on your keyboard, enter “test”, then press ‘Enter'
5. Observe the name shown in the Hierarchy
6. Save the file
7. Observe the name shown in the Hierarchy again

Actual result: The given name is not shown
Expected result: The given name is shown

Reproducible with: 6000.4.0a2 (417aa67423b3), 6000.4.0b10, 6000.5.0a7
Not reproducible with: 6000.0.68f1, 6000.3.10f1, 6000.4.0a1

Workaround: Changing the custom VisualElement to use “UxmlElementAttribute”

Element gets renamed successfully, however the name is not shown in the Hierarchy
Deprecation warnings are shown in the Console for the affected VisualElement starting with 6000.4.0a1
