Popup triggers criticals
Clicking the popup triggers criticals a lot of the time:
(squeekboard:7016): Gtk-CRITICAL **: 14:56:23.701: gtk_render_frame_gap: assertion 'xy1_gap <= height' failed
This is related to the gap between the rectangle the popup points to and the popup itself. It seems like a bug in GTK occuring maybe when the rectangle is near the bottom of the widget. There's nothing out of the ordinary with anything else about the params.
