Hitting a minecart or a boat with a mace enchanted with wind burst will trigger the effect, launching the player upwards. I believe this is a bug, since smash attacks cannot be performed on vehicles, and making use of this enchantment on these entities will trigger MC-272948.

How to reproduce

1. Get a mace enchanted with wind burst.
2. Place a boat.
3. Launch yourself upwards with a wind charge.
4. Hit the boat while airborne.

Expected result
The player doesn't get launched into the air.

Observed result
Wind burst is triggered, even though a smash attack wasn't performed.
