And I see also that keyboard.c does seem to do it right:
if (CONSP (c)
&& (EQ (XCAR (c), Qselect_window)
#ifdef HAVE_DBUS
|| EQ (XCAR (c), Qdbus_event)
#endif
#ifdef USE_FILE_NOTIFY
|| EQ (XCAR (c), Qfile_notify)
#endif
|| EQ (XCAR (c), Qconfig_changed_event))
&& !end_time)
/* We stopped being idle for this event; undo that. This
prevents automatic window selection (under
mouse-autoselect-window) from acting as a real input event, for
example banishing the mouse under mouse-avoidance-mode. */
timer_resume_idle ();
Hmm...

Can you try to run Emacs under GDB?
Then start Emacs to try and reproduce the problem with mpv.
Once ready to start mpv, hit `C-c C-z` in GDB, then type
break timer_stop_idle
continue
then launch mpv and try to see the backtrace (with command `bt`) when
the timer_stop_idle breakpoint is triggered.
[ Then again, maybe this will trigger all the time, but is a false
alarm because it would be undone right after by the above code. ]
