Mobs can't get on the minecart

English ver.

When I was tying to carry villagers to another place, I found that villagers can't go on the minecart but they can go on the boat, even they are right next to the minecart. Then I realized every mob can't get on the minecart unless the fall on to the minecart. I don't know if this is a bug.

当我想把村民送到另一个地方时，我发现他们只会坐船而不会坐矿车，然后我试验的时候发现除非生物直接掉落在矿车上面，不然所有的生物都不会坐矿车。我不知道这是不是一个bug。
