When focusing the button on the recent workspace feature it announces dirty, however it should do this when you're navigating the list, not when just navigating between items. Otherwise the only way to tell if it has backups/changes is to tab into close the editor.

Needs verification in:

• editor picker (edt)
• files picker (e.g. having a dirty editor in history)
• window switcher (Window > Switch Window) when having dirty files in that window
• recently opened (when having dirty files in workspace)
