UI Toolkit window performance regression when resizing/docking windows on Windows with Editor Font set to System Font/Verdana

1. Create/Open any Unity project
2. Make sure "System Font" Editor Font is selected in Preferences
3. Open Window -> UI Toolkit -> Samples
4. Resize/Dock the Samples window, observe performance
Expected result: Resizing/docking the Samples window is smooth with no visible performance issues
Actual result: Editor lags very noticeably while resizing/docking the Samples window
