Confirmed. This likely happens because (or is a side effect) of the dragon having 9 hitboxes. If you enable F3+B, you can see that the dragon consists of 8 hitboxes contained inside of the main, big hitbox.

Why "Wont Fix" it was not the case in 1.13.2 and before.

Why it's resolved as "Won't Fix" any explication ?

works as intended would be better than "won't fix", saying wont fix as if its not important
Well, it doesn't work as intended, so that resolution doesn't make sense.
I cannot replicate this problem in snapshot 24w11a. It appears that it has been resolved at some point, even though it was marked as "won't fix."
