Crimson and Warped trees do not check for empty space when growing

The Bug

As supposed to any other sapling or big mushroom, crimson and warped trees do not check for empty space when growing.
This means their height is not defined by blocks above and growing never fails, even if there is an insufficient amount of space.

Steps to Reproduce

1. Place a warped or crimson fungi
2. Place bocks above it
3. Bone meal the fungi.
   → Tree will grow disregarding any blocks above
