The bug

On bedrock edition, there were some blocks that required an block underneath to be placable, like for example pumpkin, jack o lanterns fence gates and turtle eggs. 1.16 was supposed to remove this, so you can place these blocks floating and don’t need a block underneath to be placable, however turtle eggs are still affected.

How to reproduce:

1. Build a wall
2. Try to place a turtle egg floating at the wall
   You can’t place it, but with fence gates, pumpkins and jack o lanterns it works.

Expected result: Turtle eggs can also be placed floating.
