Cursor sometimes remains in resize state when dragging to the UI Builder “Add Class” window

Steps to reproduce:

1. Create a new Unity project using a 3D Universal Template
2. Create a UI Document (Assets > Create > UI Toolkit > UI Document)
3. Double-click on it to open in UI Builder
4. Add a Visual Element to the Hierarchy by dragging it
5. Select the Visual Element and expand the "Text" foldout in Inspector
6. To the left of the Size property, click on the three dots next to it
7. Select "Extract Inlined Style to Selector" > "New Class…"
8. Drag the cursor to the Add Class window
9. Observe the cursor style

Actual results: The cursor briefly remains in the resize style (resize cursor)

Expected results: The cursor switches to the normal/default pointer instantly

Reproducible with versions: 6000.0.66f1, 6000.3.5f1, 6000.4.0b5, 6000.5.0a5

Tested on (OS): Windows 11

Note: Does not matter what property is selected in the 6th step, just so that it has the "Extract Inlined Style to Selector" option
