Thanks for the fix on master, Paul. I can confirm that it works fine
with GTK+ master.

We're not talking about GTK4 here. GTK+ master will be released as
3.22 in the fall. But I am getting reports about various other
problems that are caused by the reversal on the gtk-3-20 branch, so I
may have to put the problematic (for emacs) back in the 3.20 branch.

If you consider the patch too risky to put in the emacs 25 branch at
this point, an alternative might be to put a release note to inform
distributors about this incompatibility and point them at the commit,
so they can pick it up if they want to ship emacs 25 with gtk 3.20.
