Issue description

The 3d gizmo doesn't update, when a collisionpolygon3d's polygon is changed in the inspector.

Steps to reproduce

• open the project: 3d-gizmo-doesn't-update-collisionpolygon-3d-inspector-change.zip
• in the scene panel, select: CollisionPolygon3D
• in the inspector, unfold the Polygon, PackedVector2Array
• increase the first point's y value, either by typing a new value: 1.0 or drag right on the value

Issue:
The 3d gizmo handle on the top left point doesn't move, even though the collision polygon's vertex moved.

Expected:
Update the 3d gizmo's handle to follow the vertex.

Notes:
The 3d gizmo's handle updates when:

• clicking on another 3d gizmo handle
• clicking or dragging on the moved CollisionPolygon3D vertex without a 3d gizmo handle
• clicking on the CollisionPolygon3D in the viewport
• deselecting and selecting the CollisionPolygon3D

The CollisionPolygon3DGizmoPlugin is updating when the polygon array is changed.

What isn't updating is the handles from the generic and external Polygon3DEditor that is shared for editing many other 3d polygon classes. That editor only (re)loads when the actual node is selected as it relies on the active process mode to update its dragged handles.
