Video showing the problem, neither forwarding a space nor returning it as False works.
In the Search Entry in gtk4-demo sending a space with forward_key_event()
produces the letter “n” instead of “ ”, sending the space key
by returning False from do_process_key_event() puts the space *before* the
committed string, i.e. typing "a " results in " a" when the space is send
by returning False.
[mfabian@fedora ~]$ rpm -qf /usr/bin/gtk4-demo
See attached video.
As I said before, currently ibus core calculates the keycodes from keysyms if engines forward keycode=0 and it's no longer handled in gtk4.
The following change works fine with me.

I mean ibus in Xorg. I don't discuss about the issue in mutter yet.
