      The bug

      When entering The End for the first time, immediately placing an end crystal on the obsidian platform will prevent the ender dragon from spawning, and also generate the exit portal, skipping the need for the dragon fight altogether.

      How to reproduce

      1. Obtain an end crystal
      2. Enter an active overworld end portal
      3. Place the end crystal as soon as you enter the end dimension

      Observed results

      The ender dragon will not appear, and the exit portal will be generated already.

      Expected results

      Placing an end crystal shouldn't prevent the dragon from spawning, and the exit portal should only be generated/activated when the dragon is defeated.
