I presented the snap problem for James Henstridge, and he gave me a very
useful hint: The Chromium snap makes use of the bionic library stack
(the gnome-3-28-1804 snap) including the im module installed by fcitx-
frontend-gtk3, i.e. the fcitx 4 gtk im module.

That made me think of <https://bugs.debian.org/977203>. That bug is
still open, and as a result im-config currently sets these variables for
fcitx 5:

GTK_IM_MODULE=fcitx5
XMODIFIERS=@im=fcitx
QT_IM_MODULE=fcitx5

It means that it explicitly looks for the fcitx 5 gtk im module, while
Chromium only has access to the fcitx 4 one.

So as a test I tweaked im-config to set:

GTK_IM_MODULE=fcitx
XMODIFIERS=@im=fcitx
QT_IM_MODULE=fcitx

and that made a difference. With that environment I could successfully
input beautiful Chinese characters in Chromium using fcitx 5. :)

Consequently there seems to be no need to add any extra stuff to
apparmor to handle fcitx 5. Instead I see two options:

1. Change im-config's variable assignment, or

2. somehow add the fcitx 5 im modules for gtk and qt to the snap library
stack.

I'm going to consult with Debian's input method team about which route
is preferable.

@James: Do you see a problem from your POV with adding the fcitx 5 im
modules to the snaps?

Bug description:
  In Debian 11 Fcitx 5 will be the default IM framework for Chinese on
  non-GNOME desktops. I can think it's time to make the equivalent
  changes in Ubuntu 21.10 as well.

  I'd appreciate input on the topic from the Ubuntu Kylin team as well
  as other Chinese speaking users.
