Focus change required for virtual keyboard to work

[hrdl-github]

regreet 0.1.1, sway 1.10+wlroots 0.18.1, also sway 1.9+wlroots 0.17.4

Trying ReGreet on a touchscreen-only device, I've noticed that keyboard input using squeekboard does not work as intended. zwp_text_input_v3 enter is not called until an input field is selected AFTER a window focus change has taken place. This is not the case with gtkgreet.

swaymsg -t get_tree |jq yields the same result after touching the text input the second time, so the surface focus logic in https://github.com/swaywm/sway/blob/master/sway/input/text_input.c might be relevant here.

To reproduce:

Start via greetd/sway:

for_window [app_id="apps.regreet"] fullscreen disable
exec "gsettings set org.gnome.desktop.a11y.applications screen-keyboard-enabled true"
exec "squeekboard"
exec "WAYLAND_DEBUG=1 regreet -l trace 2> /tmp/regreet.log; swaymsg exit"
include /etc/sway/config.d/*

Then

1. Press the edit user button using touch input
2. Press the user name field using touch input. The keyboard is toggled, but no zwp_text_input_v3#.*.enter event is received. Keyboard input via squeekboard is not received.
3. Via ssh, run SWAYSOCK=/run/user/*/sway*.sock swaymsg focus parent
4. Select the user name field using touch input. Not until now the zwp_text_input_v3#.*.enter event is received.

I don't have a touch-enabled device to test this out 😅. I tried this same setup on my Arch desktop, but squeekboard wouldn't pop up. I had to type with my physical keyboard. Is it actually supported on desktops, or only on touchscreen-only devices?
