Players' position updates incorrectly in certain circumstances (poor prediction system)

When a player is walking or jumping on the edge of something, or is in the middle of the air, it sometimes bugs out and the players' collision box is lower than it should be for a split second, or the players' position just straight up updates poorly, and incorrectly. This is really annoying to work with when making maps, and is one reason why knockback in MCBE vanilla PVP is really buggy. (Look at attachment for a parkour-type example and a better understanding). Note that in the attachment, the only time the player should get teleported back is when it goes into that red ring below the platforms.

Update (made during 1.20.30): Now that I spent more time understanding Bedrock’s vanilla movement system, I can now say that there are countless ways that you can trick the game into being somewhere you aren’t. It’s all due to the really outdated player movement prediction system. If anyone wants more videos of me tricking the prediction system, lmk. I’ll share them all in here.
