Pointed Dripstone still deals damage when certain blocks are on top of them

The bug:

Jumping on certain non-full blocks like Carpets and Trapdoors with Pointed Dripstone underneath them causes damage to the player.
All blocks that cause this:

• Trapdoors (wooden & iron)
• Carpets (wool & moss)
• Brewing Stand (when on lower part)

How to reproduce:

1. Place Pointed Dripstone facing up.
2. Place one of the listed blocks on top of the Pointed Dripstone.
3. Go into survival/adventure mode and jump on top of the block you placed.
   →  You still take damage.

Expected Behavior

The barrier the block provides between the player and the Pointed Dripstone should prevent the player from getting hurt.
