Windows Mixed Reality - Swimming = floating forever

I have been playing Minecraft with my Windows Mixed Reality headset and I'm loving it, except for one experience-breaking bug: the inability to swim. My world started me on a small island in the middle of an ocean. As such most natural resources are limited to the underground and what the sea provides. Unfortunately, I cannot swim.

 

Attempting to swim almost always results in floating high into the air, or floating on top of the water, and being unable to stop floating until I save and quit and load the save again. Anything that would require me to swim is not possible. I have had this happen while sprint-swimming and walk-swimming.

Here is a link to the video I captured of the bug. https://youtu.be/cY8-XAtjdYk
