Viewport's gizmos for Margin and Padding disappear when dragging to modify the value and the cursor leaves the Spacing section

Steps to reproduce:

1. Open the attached project
2. Open the NewUXMLTemplate asset
3. Select the VisualElement in UI Builder's Hierarchy tab
4. In the Inspector window, expand the Spacing section
5. Using the Margin/Padding gizmo, drag the Top Margin Value to modify its value
6. Observe the Margin gizmo in the Viewport as you drag the cursor

Actual results: The margin gizmo disappears as soon as the mouse cursor leaves the Spacing section in the Inspector

Expected results: The margin gizmo in the Viewport remains visible the entire time while the value is being modified by dragging
