[MCPE-183818] /inputpermission causes players to fall through blocks at certain heights

At certain world heights, using inputpermission will cause the player to clip through the block below them.

In the testing that I have done using the command

/inputpermission set @s movement disabled

Whilst at world heights y = 255 || 256, will cause the player to clip through the block below them.

This bug does not occur at world heights 257 || 254.

I have attached a video example of the bug.
