Steps to reproduce:

1. Create a project
2. Window->UI Toolkit->UI Builder
3. Go to the "Controls" window and find "Button"
4. Double-click on it
5. Verify, that button becomes added 
6. Select it
7. Verify, that its data becomes displayed in the "Inspector" window
8. Find the "Attributes" section 
9. Expand it and observe its fields and how they are stuck to the right edge
10. Also, observe "Data Source Path" and one more field above.

Actual Result: Some fields in the "Inspector" window have margins and are aligned. Some not. Added screenshot in the "Attachments" section.

Expected Result: All fields should have the same margins and should be aligned from both sides.

Reproducible with: 2023.2.0a9 (FAV), 2023.2.0b10, 2023.3.0a5.

Not Reproducible with: 2021.3.30f1, 2022.3.10f1, 2023.1.11f1, 2023.2.0a8.

Note: Would be good that all fields would be reviewed and aligned.
