I can't say why, but today this works fine with my "normal emacs"; with
all packages loaded and running as server/client.

When I start with emacs -Q then it does not work; it needs two calls to
select-frame-set-input-focus.

I thought it might have something to do with focus and how WM raises
windows and gives focus; normally I have focus follow mouse but not auto
raising enabled. I have disabled auto-focus (need click into window to
give focus) but I see no difference in behaviour.
