AFAIU, currently this could only be handled if the user has a font
that can display both those Emoji_Presentation=No characters and those
Emoji_Presentation=Yes. In the future, we could perhaps improve that
by modifying the logic in fontset.c.
I think the presentation of the Emoji appearance for non-Emoji
characters followed by VS-16 is less important than being able to
display sequences of Emoji characters, so we will be doing OK, IMO, if
Emacs 28 only supported the latter.
