event as something that happened on the tool or tab bar since
that would break mouse dragging operations that originate from
an ordinary window beneath and expect the window to auto-scroll
as soon as the mouse cursor appears above or beneath it
(Bug#50993). Since this "fix" might break track_mouse based
operations originating from the tool or tab bar itself, such
operations should set track_mouse to some special value that
would be recognized by the following check.
This issue should be properly handled by 'mouse-drag-track' and
friends, so the below is only a temporary workaround. */

we use to display those, and it wants frame-relative
