We now found the underlying bug: The ControlsManager (which causes the bad call to `_updateWorkspacesFullGeometry()`) is getting (re-)allocated while we add the view to the overviewGroup actor because the overviewGroup is already visible and the view is immediately getting mapped by `clutter_actor_add_child_internal()`. That causes a resource-scale calculation and that indirectly causes a call to `_clutter_stage_maybe_relayout()` (explained more detailed in the last commit). So now that we got rid of the immediate relayout happening when mapping the view, we can revert this fix. This reverts commit 6cc19ee6f05102baef39b8a1bec73eff06699879. https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1315
