PolylineVolumeGeometry at vertical direction

When I use PolylineVolumeGeometry to draw pipes vertically，the result is a plane, is not like it's horizontal.
It is too cumbersome to use cylinder and polylineVolume as a combination. I don't know if our team is considering supporting him in the future, or if I used it wrong.
it's all. thank you!

Start by reproducing the reported PolylineVolumeGeometry case with a vertical pipe and compare it with the horizontal result. Investigate the PolylineVolumeGeometry entry point and determine the intended behavior for vertical directions; done means vertical pipes render as volumes rather than planes.
