Description of Bug and Steps to Reproduce

During work, switching locales stops working; at the same time, the locale indicator switches. It stuck on English locally only and never stuck on other locales. I usually use ctrl-space to switch, but I can also use CapsLock, but it's not different.
I can restore it to normal only if I manually change the locale in the KDE system tray dropdown menu.
Everything is fine with Konsole and other applications.
It can work fine for 10 minutes before it starts to stick. I think it's difficult to reproduce.

WAYLAND_DEBUG=1 foot -d info 2> foot.wayland.log

I didn't do Wayland logging yet, I will try to do it soon.

Relevant logs, stacktraces, etc.

No response

Okey, I have the logs now. At the beginning of this log, the locale switch didn't work, but at the end, it started working again.

I did a few more tests - it seems like the foot lost the zwp_text_input_v3 "connection" and just uses English as a fallback.
I can change locale by fcitx5-remote -t and I can confirm it by fcitx5-remote -n but it's not affect to foot, also I didn't see zwp_text_input_v3.commit_string() and see only wl_keyboard.key() during this time.

Seems like it's this issue https://bugs.kde.org/show_bug.cgi?id=493098 but I don't understand why it's not a case for konsole?

Okey, seems like I figured out what happened. It's how switching workspaces works in the context of IME.
I will provide PR.
