[Bug]: The liquid will not leak from the bottom of the container when it is placed close to the ground, but it will seep out in a container that is suspended in the air.

[Kawhi5]

Bug Description

When the height parameter of the container is 0, the liquid inside will not leak. However, as the height of the container is increased, the liquid will leak from the bottom.
