Subject: [PATCH] ui/gtk3: Fix SEGV when commit an emoji on Emojier in Wayland
Just pressing Space key without emoji annotations can launch Emojier
popup and the popup takes a focus in Wayland and the chosen emoji is
output when the original text application gets the focus after Emojier
popup release the focus. Emojier disabled Ctrl-Shift-e after got the focus.
But currently GNOME Wayland has a bug not to send focus-in until a
key press or mouse click happens [1] and Emojier causes a SEGV.
Now Emojier disables Ctrl-Shift-e immediately when an emoji is chosen
whether focus-in comes or not and fixes the SEGV.
