This is because Emacs automatically moves the point when it’s in the
middle of text with the ’composition’ property.  See (elisp) Adjusting
Point in the Elisp Info manual for more information about this feature.

It seems that post-command-hook is invoked _before_ the point is moved,
so querying the position of point inside post-command-hook does not
always give correct results.  You could add your code to the
pre-redisplay-function instead.

About what you propose, I think that showing the name of the Emoji under
point may be a good new feature of emoji-list.  What do others think?
