Comment 16 for bug 1958492

Reverting /usr/share/ibus/component/mozc.xml to default and adding the following configuration didn't work in Ubuntu 20.04.

$ cat ~/.config/mozc/ibus_config.textproto
engines {
  name : "mozc-jp"
  longname : "Mozc"
  layout : "jp"
}

$ apt show ibus-mozc
Package: ibus-mozc
Version: 2.23.2815.102+dfsg-8ubuntu1
