Entities do not spawn into the overworld correctly when going through the end exit portal

When entities other than players (mobs, falling blocks, items, etc) come through the exit portal, they do enter the overworld at world spawn, but at Y level 32767. 

This screenshot was taken with another player loading the exit portal chunks and a command block summoning primed tnt above the portal

This issue was first encountered on a realm with players from windows, ps4 and xbox one.

This was recreated for testing in a standard multiplayer world with players from windows and ps4
