      The Bug

      Clicking a dragon egg on a low enough block means the egg has a chance to teleport into the void. Dropping an egg through a hole in the world, one can see it fall. Clicking the egg on the other hand, simply makes it teleport down into the void.

      Steps to Reproduce

      1. Create a Superflat world: 
        minecraft:glass;minecraft:plains
      2. Place a dragon egg.
      3. Right-click it to make it teleport.
      4. Note that the dragon egg will be teleported below the lowest built height.

      Code Analysis

      Code Analysis provided by Thumpbacker

      Adding a check using level.isInWorldBounds(blockPos) in the teleport method if statement fixes this issue.

      So instead of the check being level.getBlockState(blockpos).isAir() && worldborder.isWithinBounds(blockpos) the check would be
      level.getBlockState(blockpos).isAir() && worldborder.isWithinBounds(blockpos) && level.isInWorldBounds(blockPos)
