Texture Preview disappears and value changes for Internal Texture Variables after assigning the UI Document Asset to a Panel Renderer in a Scene

Steps to reproduce:

1. Open any Project
2. Create a UIDocument Asset in the Project Browser and open it in UI Builder
3. Add a Visual Element to the Hierarchy and select it
4. For a Texture Property choose "Set variable" in the kabab menu on the left side of it
5. Hover Cursor over the available internal Texture Variables
6. Create a Panel Renderer Game Object in a Scene's Hierarchy and assign this UI Document to the Panel Renderer
7. Repeat steps 4-5 and observe the Variable Previews

Actual results: Value changes of the Internal Texture Variables and their Preview is no longer shown, removing the Preview feature making users rely on on the Value only

Expected results: Texture Preview is always visible in the Variables Selection Dialog for Internal Variables
