Fix drag event leaving the gizmo not under the cursor highlighted
Prevent drag events from changing the highlighted gizmo
unless the drag event activates the gizmo.
This resolves a glitch where testing a drag event would highlight
at the point the drag was initiated even when the event was not handled.
