Projectiles pass through entities sometimes

Sometimes projectiles pass through mobs. This bug seems to happen more at close range, and can seriously mess up both Survival and PvP.

 

This is a major bug that should absolutely be prioritized for the 1.16.4 update.

NOTE: Though this was tested on a realm against players I can confirm this happens with any entity even in single player
