The issue with the water floating is MCPE-34237.

The underlying issue here is that the game stores the player's Y-location at +1.62001 from the player's feet. This, or the failure to adequately code around it, has been the source of numerous bugs, including MCPE-31896 (which covers multiple issues), MCPE-41398, MCPE-28765, and MCPE-79250 / MCPE-19110.
