I think the problems only appear if the list of emojis becomes empty.

Here I get the normal/expected behavior and I do have
`fonts-noto-color-emoji` installed but on the machine where I see the
problem that package is indeed not installed.

So I guess to reproduce the problem you need to use a machine that
has sufficiently few fonts that the list of emojis becomes empty in the
category that you select (such as "smiling smileys").
