When a dying mob fall over and hits the ground, it continues to slide along it rather than stopping in place. The direction is usually similar to that which was active before contacting the ground, but not always identical. The effect appears to be dependent on the mob.

I concur with PC_screen's analysis. This and MCPE-37789 are the same, it's just that the behavior is more pronounced with mobs that normally jump. The issue is not a lack of friction, it's that pathfinding remains active while mobs are dead. Here is a video of a fleeing dead rabbit:

This issue together with MCPE-74963 is also the cause of MCPE-49418.
