[UI Toolkit] Style changes applied with USS are overridden when the style is set through a script
How to reproduce:
1. Open the attached project "tint repro"
2. Open the scene "SampleScene" and enter Play mode (Assets/Scenes/SampleScene.unity)
3. In the Game view, click the red checkmark
Expected result: The checkmark color is tinted green
Actual result: The checkmark color remains red
Reproducible with: 1.0.0-preview.15, 1.0.0-preview.17 (2020.3.31f1), Built-in (2021.2.16f1, 2022.1.0b12, 2022.2.0a8)
Could not test with: 2019.4.36f1 (No UI Toolkit), 1.0.0-preview.14 (2020.3.31f1) ('DefaultEditorWindowBackend' does not implement interface member 'IEditorWindowBackend.overlayGUIHandler')

Resolution Note:
The Image component does not offer a way to unset style overrides made directly on the instance, in C#.
Unfortunately this limitation is common to all custom style properties in UI Toolkit.
We intend to revisit this functionality at a later date but we have decided to mark this issue "Won't fix" in the meantime.
A workaround is discussed in the forum thread: https://forum.unity.com/threads/inherit-image-tint-color.1211376/
