Steps to reproduce:
1. Create new Unity project using Universal 3D Template
2. In Hierarchy create Button element object (Right-click > UI Toolkit > Standard Elements > Button)
3. In “Open UI stage” pop-up press “Continue” and save UXML file
4. Once Button element is created, observe it in the UI Viewport window or Game view
Actual results: “Button” text is missing on the Button element
Expected results: “Button” text is not missing on the Button element
Reproducible with versions: 6000.6.0a7
Can’t test with versions: 6000.6.0a6 and lower (No such feature to create UI Elements in Hierarchy window)
Tested on (OS): macOS Tahoe 26.4.1 (M1)
