launcher leaves focus nowhere after Alt+F1, Esc

Binary package hint: unity

After using Alt+F1 to navigate the launcher with the keyboard, then pressing Esc to cancel this mode, the focus is left nowhere. The top panel is blank, and does not show any menus when rolled over. Keyboard input appears to go nowhere.

It seems reasonable to expect focus to return to where it last was, before Alt+F1 was pressed.
