additional information:
Seems that IM module (like /usr/lib64/gtk-3.0/3.0.0/immodules/im-fcitx5.so or /usr/lib64/gtk-3.0/3.0.0/immodules/im-ibus.so) isn't loaded at all, when using Wayland.

Still present in #120034 (comment)
Maybe waiting a newer electron 12.x release?

It may get support in electron 14 ( chromium 93 ) or later. electron 12 ( chromium 89 ) or electron 13 ( chromium 91 ) don't support it.

ibus not working at all under wayland because not support the latest version of the protocol.

Does Electron or Chromium currently supports text_input_unstable_v3 or text_input_unstable_v1 protocol?

It support text_input_unstable_v1: https://github.com/chromium/chromium/blob/master/ui/ozone/platform/wayland/host/zwp_text_input_wrapper_v1.h

Basically, current Wayland protocols not enough for normal IME but developers working on it - https://gitlab.freedesktop.org/wayland/wayland-protocols/-/issues/39
