Element's Name field clears and the name is not saved when saving the UXML immediately after typing the name in the Inspector

Steps to reproduce:

1. Create a new 3D URP project
2. In the Hierarchy, right-click > UI Toolkit > Standard Elements > Visual Element
3. Save the new .uxml file
4. Observe it opens in context
5. Select the Visual Element
6. In the Inspector, enter any name
7. Without pressing Enter/Return, press Ctrl/Cmd+S (or File > Save)
8. Observe the name field

Actual results: The name field clears and is not saved

Expected results: The name is committed on save and remains in the Name field

Reproducible with versions: 6000.6.0b1, 6000.6.2f1, 6000.7.0b2

Can’t test with versions: 6000.3.24f1 (in context editing not available)

Tested on (OS): Ubuntu 24.04, macOS 26.5

Notes:

• Name is saved when inputting it the second time
• Does not reproduce if Enter/Return is pressed in the Name field before saving - the name is only lost when the field is still uncommitted at save time
