How to reproduce:
1. Open the user's attached "UI Elements Bugs.zip" project
2. Open the "SampleScene" Scene
3. Select the "Test Object" GameObject in the Hierarchy window
4. Edit any "Test Script (Script)" Component's field in the Inspector window
5. Manually change the field back to the value it was before editing it in the Inspector window
6. Right-click on the field and press "Revert"
7. Observe the field in the Inspector

Expected result: The label of the field changes back to the way it was before editing the field
Actual result: The label of the field is still bold after pressing "Revert" (Indicating that the value has been modified)

Reproducible with: 2019.4.10f1, 2020.1.5f1, 2020.2.0b3
Could not test with: 2018.4.27f1 (UIElements are not supported)

Note:
- If the "Test Object" GameObject is unselected and then selected again the field's label will not be bold
