So now we essentially only inhibit the premature resize for toplevel
windows, where it is most crucial. For popups, this didn't work for two
reasons: we relied on the owner of the popup (application) to resize
according to the configured size. For custom popup operators like
Epiphany and LibreOffice, this didn't work out well, since they simply
didn't.
Making gdk do it for them in case they didn't themself did make the
popups show up properly, but there were still some weirdness in
LibreOffice where tooltips didn't still didn't get the right size. So,
even though the size set by application may be different from the one
later configured by the display server, let the applications have their
way and see their resize result immediately. It's fairly likely to be
what they eventually get anyway.
