Creepers lit with a flint and steel do not count as a playerkill

If a player detonates a creeper using a flint and steel the resulting explosion does not count as a playerkill/playeraction. zombies and drowned do not drop iron, copper or tridents, sculkblocks or ores do not drop xp and some items get destroyed in the explosion among other things.

I found this inconsistency whilst doing some testing in the new snapshot although the issue is also present in 1.18.2.

im not sure what the expected behaviour here is suppost to be but i assume since the creeper is lit directly by a player it should count as a playerkill/playeraction.
