Changing values for the Time, Length & Angle Variables of a USS selector causes significant lag and defers other edits in the UI Builder's Inspector

Steps to reproduce:

1. Open any Project
2. Create a UIDocument Asset in the Project Browser and open it in UI Builder
3. In the StyleSheets panel create a new USS and select the :root selector
4. In the Inspector Variable list create a Time, Length & Angle Variables
5. Try holding down a character or number button when editing the Variable's value

Actual results: When entering or changing Values for these Variables significant lag can be observed, other changes in the Inspector will be deferred until these changes are applied to the Variables

Expected results: Changing values in the Inspector does not cause lag nor defer other edits in the Inspector
