Apparently that happens.

Taking away gravity (more precisely, removing buoyancy effects) can cause all kinds of interesting behavior. It's possible that the fluid will not remained confined within a container- if the fluid does not wet the container walls, the fluid may be driven out of the container.

It's also a problem for porous media- a specific application is soil/hydroponic media- the fluid surface is not uniquely defined, and so water may not get transported to the roots of a plant. If there is a porous filter barrier in a fuel or water line, the fluid may not pass through unless there is sufficient pressure to drive it.
