This appears to happen only when the Overlay is used. We've already got the logic in place to hide the standard Toolbar for editors which supports fullscreen modes, so this patch simply adds #admin-menu to the list of elements to show/hide.
That patch seems to fix the issue for me. Many thanks.
As a possible follow-up improvement (in a separate issue), we could investigate to provide central API helper methods for this, in order to decrease the amount of duplicated code.
Thanks for the quick review, sorry it took me a month to patch this.
I've committed this to all major branches and the -dev snapshots will be updated within 12 hours and this will be part of the next official releases..
EDIT: Yes, a central utility function sounds good.
Follow-up in #1927000: Add utility functions for fullscreen mode management.
