Unlogging on a glass block above a lava pool may result in logging back under bedrock

What I did :

• create a 3x3 pool of lava above the ocean (ocean and lava part is important)

• a few air blocks above this create a 3x3 glass or leaves platform

• logout on the glass/leaves platform

• log back in under bedrock (you get "fall out of the world" death) or sometimes in the ocean.

 This is 100% reproducible on realms.

 

Lava is the important part, I tried to put water instead of glass blocks and I would log back on the same block I logged out.

 

I already talked about this bug in MCPE-38374 but you asked for a new bug entry.

 

Since it might be relevant, I only tested this with a phone over cellular data.
