Expected behavior

The expected behavior is for this to not break gameplay, and especially not in a single-player world. I'm disinterested as to what the exact implementation for such a prevention method would be.

Actual behavior

Entities will tick rapidly in a short duration, "catching up" with the server. This is as awful as it sounds, as there's nothing you can do to prevent it or react.

For example, if you're fighting an enderman: it freezes, then attacks 10 times in an instant, unquestionably killing you. A skeleton may rapid-fire arrows. A creeper may blow up spontaneously.
