That is, you can interleave normal and -Q sessions and in the normal
session "this works" and in the -Q session it doesn't?  Then I'm afraid
that you have to bisect the things you do in your normal session to find
out what makes "this work".

By design, auto-focus should only affect mouse movements.  One recurring
problem is, however, whether the WM should auto-move the mouse pointer
to a freshly displayed window in order to make sure that if the mouse
pointer was located on another window, that window would not regain
focus immediately due to your auto-focus settings.  Note that that
window _should_ retain focus when you specified 'no-focus-on-map' for
the new frame but IIUC you did not do that.
