    Description

      The bug

      When a mushroom grows into a giant mushroom, the blocks the giant mushroom consists of don't send block updates to adjacent blocks. Observers trigger properly though.

      This happens both with red and brown mushrooms.

      To reproduce

      1. Build the test setup seen in this screenshot:
      2. Place a red or brown mushroom on top of the podzol
      3. Use bonemeal on the mushroom until it grows
      4. The Redstone lamp won't activate:
