Hide context menu within reuse library view
The reuse library view displays the reuse libraries (and their reuse elements). When the user right click on them, a context menu appears with "Delete Library" and "Rename Library". When the dialog box opens for the respective action, the context menu should disappear (be hidden) like it was done/implemented for the context menu in the component architecture editor (see #4321 (closed)).
Under Linux, it seems that the context menu does not disappear even after the dialog and action has finished.
