Tight-mesh sprite with DynamicColor doesn't update its unity-background-image-tint-color

Steps to reproduce:

1. Open attached project
2. Open the "MainMenu" Scene
3. Navigate to the settings menu
4. Hover over the top buttons
5. Open the UI Toolkit Debugger
6. Navigate to the button icon (game controller or other)
7. Change the -unity-background-image-tint-color

Actual results: The color doesn't update

Expected results: The color should update. Removing the DynamicColor hint seems to unstuck it.
