[MC-115750] Advancement "Monster Hunter" (kill_a_mob) is not granted for killing certain hostile mobs

The advancement "Monster Hunter" is granted for killing many types of hostile mobs, including polar bears, but is not granted when you kill:

The reason for this seems to be that the corresponding JSON file is not containing the case for killing these creatures.

Revoke the "Kill a mob" advancement

/advancement revoke @p minecraft:adventure/kill_a_mob

Killer rabbit is intended, or Monster Hunted advancement are unobtainable in survival.

Killer rabbit is intended

Source? That a hostile mob doesn't spawn in normal gameplay, doesn't make it intended that it doesn't give the advancement.

Ooh. Sorry, I'm thinking that it is problem with kill_all_mobs advancement.

Awesome, you marked mine as a duplicate, but its still not actually resolved in game.

In line with MC-121148, wolves shouldn't be on the list.

Note that Wolves and Polar Bears are intentionally not included.
