Quitting game in nether on glass causes you to restart on the bedrock roof.

On a platform of glass blocks, I can consistently quit the game, and restart and I end up on the roof of the nether. Since you can't break through bedrock, you end up stuck up there until you can die of hunger.

Easy to reproduce: Go to the nether, place down glass blocks. Stand on the glass, quit game. Rejoin the game and stuck on the roof.

Thanks!
