### Problem

On global pages you still have the opportunity to collapse or expand the sidebar via the arrow in the middle of the sidebar or by resizing it. But when trying to resize the window size with a collapsed sidebar, the side menu will be expanded automatically. This is due to an window resize listener which is incorrectly handled.

### Expected behaviour

The sidebar should Begin of the insertionnotEnd of the insertion be Begin of the insertionaffected by a window resize.
