The wind burst enchantment sometimes fails to launch the player when hitting mobs while above an open trapdoor or fence gate

Occasionally, hitting an entity with a wind burst mace while above a trapdoor or fence gate prevents the wind burst explosion from launching you upward.

How to reproduce

1. Dig a 2x2 hole and put 4 trapdoors inside it

2. Open the trapdoors

3. Spawn a mob close to the hole

4. Fall from a few blocks above the hole

5. Hit the mob with a wind burst enchanted mace while near the hole

6. Repeat these steps a few times

Expected result

The wind burst enchantment should always propel you into the air.

Observed result

Occasionally, the explosion from the wind burst enchantment does not launch you into the air.
