Avatar dragged to the void when tp with end gateway (apparently trapped inside a solid block)

Steps to reproduce:

• Enter to the end
• Kill ender dragon
• Go and throw an ender eye into the gateway

Expected: Tp to a safe and stable location

Actual: I'm being dragged outside the end island with a weird glitchy animation (I think I'm being teleported inside a solid block and the algorithm is trying to get me out)

I can escape if I throw an ender pearl on the platform, and I tried to fill the platform with cobblestone under the end gateway, but I'm still getting trapped in.
