CSG node gizmos are outdated after reparenting nodes to a CSGCombiner

Godot version

Issue description

When I place a CSGCombiner and add any CSG node type as children, the combiner does not update it's mesh after you switched tabs.

This is odd, I work with csg a lot, why can I reproduce it so easily now and now notice it earlier? I will reboot to see if its a memory issue or something.

Steps to reproduce

Create a new Project
Add a CSGCombiner to the scene
Add any CSG Node as child of that combiner
Change some settings of that child, see the mesh update
Switch tab to another 3d scene
Switch back
Change settings of the children
Mesh does not update anymore until you reparent the CSGCombiner

Nah, still the same after reboot.

Looking at the video, only the gizmos seem to be outdated, not the CSG mesh itself.

On the video, right at the end, you can barely see that there are faint blue lines next to the rendered mesh. Just leave this here because it is barely visible. This is the actual mesh, translated to the right, the small one at the end is still wrong. Don't know if related

Yeah you are right. wen saving the scene and reopen it, the mesh is correct. So seems to be a visual issue then, I guess

Not the same issue but might be related: #54445
