Sorry about MCPE-99693. I accidently selected all the text and then typed “et”. Anyway, I was on this world on creative mode and I managed to get an exp orb in the void. I expected it to disintegrate, like other entities, but exp orbs don’t.

How to reproduce:

1. On a flat world, dig a hole until you get to the void. 
2. Summon an exp orb in any way near the hole.
3. Put a block of stone over the hole. 
4. When the exp orb is on the block of stone, fly up and break it. 

Expected results: The exp orb disintegrates in the void.

Observed results: It doesn’t disintegrate in the void.
