Teleports greater than ~0.16 are choppy

Partner Rank: 3

Verification builds: 1.13 release, 1.14.0.50
Regression builds: None, I can reproduce this as far back as 1.2

Summary: When a mob is teleported further than 0.16 blocks during a tick, its movement is very choppy. Movements less than 0.16 blocks look nice and smooth. Stacking multiple teleports (such as teleporting by 0.1 twice for a total of 0.2) result in choppy movement as well.

Impact: This can make entity-based cutscenes distracting, ugly, or unpleasant to watch. This makes a mechanic in an upcoming map unsatisfying to use.

Repro Steps:

1. Download and open the attached world
2. Press the button between the two command blocks
3. Watch the pig and cow as they move
4. If you want, increase the value in the right repeating command block to teleport the cow more than 0.17 – it gets even more choppy

Expected Results: They both move smoothly.

Observed Results: The cow stutters as it moves, only the pig moves smoothly.
