[gtk4] Double focus in/out reports
printf '\e[?1004h'; cat
As you focus from/to another window, you get doubled focus in/out reports, like ^[[O^[[O^[[I^[[I
.
It's paritally a VTE thing, I guess it should track internally if it has the focus (it surely already does so, for cursor blinking, and for initial focus report), and then ignore requests that confirm the existing state.
But I'm filing it against g-t first, to see if there's something that the gtk4 branch does wrong.
