Yes, this is better.  But I wonder if we can do better yet.  I see
that we already have machinery in place to delay auto-selection for
some reason or other -- can we use this feature in this case, perhaps?
See mouse-autoselect-window-state and its users.  Perhaps we can delay
the auto-selection until after the key sequence started by ESC is
processed?

Ah, you mean only keys from special-event-map will have such an
effect.  Most probably, yes.
