I can't reproduce this either.  I used two builds: no-toolkit and GTK3.

Only when I click "too fast" the option doesn't expand, but if I move
the mouse, Emacs highlights a region, so I'm guessing that runs another
command and not the whole widget-button-click command.  Does that happen
to you as well?
