Thread:VisualEditor/Feedback/Not Notification If User Is Logged Out While Editing

In a wiki where a user is required to be logged in to save a page. If a page is being edited in the Visual Editor then in another tab the user is logged out of the wiki when the save button is clicked then the page responds by doing nothing but continuing to show the save button. It would be helpful if some notification was given to tell the user they need to log back in so that they can save the page.
