Agreed that it shouldn't be necessary.

And also agreed that 'compose:none' doesn't seem to be declared[1] as a valid
xkeyboard-config option.

I can confirm that the problem re-occurs after moving '~/.config/dconf/user' to path '~/.config/dconf/user.bak' and logging out and logging back in again.

compose key within a session; after relogin, it is restored to 'Left Super')
