[1.19.2][0.2.4] Willow Broom allows you to fly into blocks and start to suffocate.

Not sure how many blocks this works on. I crafted my broom in the attic of my house where I have Dark Prismarine blocks for the roof. When I got too close, I flew into the block and started suffocating rather than bouncing off of it.
