bug#44020: 28.0.50; Prefer selection of colour emoji fonts?

[Lars Ingebrigtsen]

If I start "emacs -Q" and load a file with this character:

🎉

Emacs shows that as a black-and-white symbol using the Symbola font.

If I then say

(set-fontset-font t 'symbol "Noto Color Emoji")
(set-fontset-font t 'symbol "Symbola" nil 'append)

I get a colourful party popper.

It'd be nice if this worked out of the box.  What do other programs do?
Have a huge list of fonts they prefer over other fonts?
