MC-9472Mobs underwater in minecarts can drown
If a mob is underwater in a minecart, they can drown. This seems odd to me since while a mob is "sitting" in a minecart, they only take up one block high of space, and the minecart is one block of space, and unless the water fills up the minecart there should be a half or 5/16 block of air above the minecart which would allow the mob to breath and not drown

Mobs aren't one block high when in a minecart...
Try putting a creeper or something in a minecart and then sent it through a one-block high space (the only block of "air" being the rails). It'll take suffocation damage because it's head will be in the blocks.
