(Realms) Shulker Box Crash

What is the bug?:

Able to crash multiple players on same loaded chunks.

(I tested this on realms but I haven't tested it on multiplayer servers)

I also tested this on mobile and I was able to crash my friend playing on PC while recreating the bug but I don't have a video for it.

How to recreate it?:

1. Stand on the top of a shulker box
2. Jump
3. Open the shulker box while still in mid-air

Only the audio loads after I attached the video on this website even though it's under 10MB so I just uploaded it on another site
