Soul Speed Boots lose durability and eventually break when riding minecart over Soul Soil.

Riding a minecart track placed on soul soil, boots with Soul Speed enchantment lose durability and will eventually break.

Created a very long soul soil highway for people to run with Soul Speed boots, then placed rails on top for those without to ride a minecart. Was surprised when I heard my boots break halfway through a journey.

Created a fresh pair of Soul Speed III boots and recorded a video where you can see the durability draining while riding in the cart.
