[Message part 3 (text/plain, inline)]

Dear maintainers,

With a recent build of Emacs and harfbuzz version 5.2.0 all the complex
emoji have extra spacing after them.  This space is present everywhere
the affected emoji is displayed.  One example is the interface of the
command 'emoji-search'.

Steps to reproduce the attached screenshot on 'emacs -Q':

- Type 'C-x 8 e s'
- Type "face" and then TAB twice to bring up the Completions' buffer.

All the best,
Protesilaos (or simply "Prot")
