When I was making a king of the ladder style map with friends, the spawn was at build height. We had a jump boost potion effect on, and when jumping we became invisible to everybody else.

What I expected to happen was...:
The player would remain visible throughout their jump

What actually happened was...:
When the player jumped above build height, they became invisible until they landed. Not tested in older versions.

Steps to Reproduce:
1. Apply a jump boost potion effect in multiplayer.
2. On a platform at maximum build height, jump with the effect
3. When above build height, the player will appear invisible to all other players on the server
