The bug
Death message when falling from a high place whilst on fire changed is different from 1.19.3. It used to be "<Player> fell from a high place", but now is "<Player> was doomed to fall". This seems unintentional.
To reproduce
Give yourself a fire charge.
Use the fire charge, step on the fire and take damage.
/tp ~ ~24 ~
Observed result
You die with the death message "<Player> was doomed to fall".
Expected result
You die with the death message "<Player> fell from a high place".
Any damage that can't be traced back to an entity and then dying to fall damage causes the "doomed to fall" death message which might be intentional as otherwise, there would be no other way of getting the "doomed to fall" death message
