Color is not updated after the first click when changing Label Color in the UI Toolkit Debugger

How to reproduce:

1. Open the “FC2.zip” project
2. Open the “SampleScene”
3. Open the Window -> UI Toolkit -> Debugger
4. Click on the "Pick Element" button and select any Label in the Game view
5. In the Debugger, scroll down and open the Color Picker for "color"
6. Click anywhere and drag to select a different color
7. Observe the text color in the Game view

Expected result: The color is updated to what color the mouse drags and hovers over
Actual result: The color changes to the color that was selected on click, but doesn't update after that
