No, there's something weird going on in `find-composition' here?  Eli,
could you have a look -- it's a bit mysterious.

(insert "\x263A\xFE0Flalalalalal")
=> ☺️lalalalalal

(find-composition (point)) on both of those return the composition on
the first cluster.

Now, the doc string says:

---
If there’s no composition at POS, and the optional 2nd argument LIMIT
is non-nil, search for a composition toward the position given by LIMIT.
---

So I interpret a nil value shouldn't search?

(find-composition (point) (point)) returns absolutely the same as a nil
value on the "lala" bits.
