Looping fall in unloaded terrain

I was playing in Creative mode, and I flew into an area where the chunk had not loaded yet. When I landed, the terrain loaded, but then my character began to repeatedly bounce up and down. I was unable to move my character, and could only move the camera erratically. I was only able to fix the issue by using an Ender Pearl to teleport away. Below is a video of the event.

I was able to reproduce the issue in version 19w08b. Jumping now fixes the problem; Ender Pearls are no longer required. However, the issue is still easily reproducible. Additionally, another glitch would often appear in tandem with the first, where I would suddenly start falling infinitely. I've attached another file where I repeatedly reproduce both issues.

The issue is reproducible in 19w09a as well. This also highlights a previously-noticed issue where placing blocks while a character is in an unloaded chunk causes said blocks to be overwritten when the chunks are loaded in. I've attached yet another file demonstrating these issues.

Please check if that's still an issue for you in the latest 1.15 (pre-)release.

This is fixed almost perfectly as of 1.15! There's the tiniest bounce occasionally, but no sticking like before, and it doesn't cause any trouble at all in normal play. Thank you! 🙂

I am unable to reproduce this in 1.16.2.
