Flatpak 1.15.6 based fcitx 5 + KDE wayland native input method protocol does not work

[Weng Xuetian]

Hi,
I know people may not be using flatpak 1.15.6 or fcitx5's flatpak
version, but just as a head up:

Due to https://github.com/flatpak/flatpak/issues/5614, WAYLAND_SOCKET
based wayland connection is broken with flatpak. Native version is not
affected.

There's no fix released yet. If you hit this, use native version if
possible. Or downgrade flatpak may also work.

Thanks,
Xuetian
