Steps to reproduce:
1. Create new Unity project
2. Create two extra Scenes in Project window
3. Drag "New Scene" and "New Scene 1" to Hierarchy window
4. Right click on "SampleScene" in Hierarchy window
5. Create UI Document with Assets in "SampleScene" (GameObject > UI Toolkit > UI Document with Assets)
6. Observe that "UIDocument" GO is created in "SampleScene" Scene
7. Right click on "New Scene" in Hierarchy window
8. Create UI Document with Assets in "New Scene"
9. Observe in which Scene UI Document with Assets is created

Actual results: UIDocument gets created in "SampleScene" instead of "New Scene"
Expected results: UIDocument should be created in the Scene which is selected at the current moment

Reproducible with versions: 6000.4.0b2, 6000.5.0a3
Can’t test with versions: 6000.3.2f1 and lower (UI Document with Assets not available to create)
