When killing a Breeze, no XP orbs are dropped.
Querying the players' experience levels and points show a difference (before: 5 levels, 1 point, after killing 2 Breeze: 5 levels, 12 points), but there are no orbs on the ground can could be picked up.
May be related to MC-266445? Not registering as a player kill?

I know that the fight is hectic and all but I'm pretty sure to not have seen XP orbs.
Also, two Youtube videos from experienced content creators show the same thing:

This video shows XP orbs dropping in the fashion I was expecting them to. This is strange.
I cannot reproduce the behavior you describe. Breezes always drop XP orbs in my tests.
The video you provided as evidence (https://www.youtube.com/watch?v=Ic3znljWmIY&t=884s) shows XP dropping (look at the experience bar after the cut).
Breezes do not drop items, which is expected, but if you look at the experience bar in the videos, they do drop XP. The video doesn't show the drop itself very clearly because it's been edited.
You probably just picked the experience up before you saw it.
And no, not related, that issue is just the breeze not being in the advancement criteria. You get XP, so it's registered as a player kill.
