UI Builder Inspector fails to stylize attribute display name when the attribute is defined via UxmlObjectReference

Steps to reproduce:
1. Open the attached “UxmlObjectReference Bug.zip” project
2. Open the “Sample.uxml” asset
3. Select the “SampleElement” VisualElement in the UI Builder Hierarchy
4. In the UI Builder Inspector navigate to the Attributes tab
5. Observe the Attributes tab

Actual result: SampleData is written as “Sampledata”
Expected result: SampleData is written as “Sample Data”

Reproducible with: 6000.0.0f1, 6000.0.79f1, 6000.3.19f1, 6000.5.3f1, 6000.3.0b3, 6000.7.0a2

Reproducible on: macOS Sequoia 15.7.5 (M1 Max)
Not reproducible on: No other environments tested

Note: The underlying field is a UxmlAttribute (which is stylized correctly on its own). The issue is that UxmlObjectReference does not inherit this stylization when wrapping it.
