I see.  select-window grabs the pointer, causing LeaveNotify and 
EnterNotify events with mode NotifyGrab.  The LeaveNotify event is 
ignored but when enter-exit mode is invoked with parameter enter-root, 
it does not ignore grab-related events.  Thus focus is directed to the 
root or desktop window.  When the grab ends, the induced LeaveNotify and 
EnterNotify events are ignored, so focus remains in the root window.

Possible solutions include making the enter-root handling also ignore 
grab-related events, in which case focus remains where it was when 
select-window was invoked (although the pointer may have moved), or 
making the enter-exit focus mode not ignore any grab-related EnterNotify 
events, if that feels more natural.  To me it doesn't.  Then again I 
don't use enter-exit mode (I used enter-only prior to enter-click).

This also grabs the pointer, so the mechanism is likely the same.

This is misguided.  focus-revert is intended for cases where the window 
in focus disappears.  If you want to change the focusing logic, change 
the focus mode.
