Momentum being lost when doing a critical hit

For some reason there is a bug on where u can't preform critical hits without losing momentum sometimes u even get pushed away from the mob/player you are trying to fight i believe that this bug first appeared at version 1.21.60 and still hasn't been patched from then

There is also another bug that happends on where if u spam hit a player they sometimes go through the block on there screen making it so they can't hit the other player this bug usually happens when the other player is in a corner. From what I know this bug only happends in worlds and realms and makes it really annoying to play PvP or PvE
