(bug) PointCloud BringToFront , SendToBack not working

BringToFront and SendToBack should work with pointclouds - it does not.

see attached file - you can bringToFront the red curve.
but you can not sendToBack the black PointCloud.

this is important to draw curves with pointclouds in the background.
it s great to have all new geometry above the cloud.

clearDrawOrder
layer order seam to have no effect on the display order.
either change the layer sort order (no effect)
or assign the pointcloud to diffrent layer (no effect, I thought it might be the layer-index, not the sort-order)
