Experience Orbs Dont Disintengrate In The Void

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. Lure the exp orb into 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.
