[Bug Report] Copy Trim gives Invalid Surface on a cylinder

seamless voronoi on a cylinder invalid surface.gh (16.0 KB)

What I did:
I try to make a seamless Voronoi pattern on a cylinder.
I made a repeatable voronoi pattern on a flat surface, then used Copy Trim to copy the pattern to the cylinder.

I got an Invalid surface after Copy Trim due to the seam of the cylinder.

I posted this problem before, and @HS_Kim helped me find a solution.
Now I like to report this as a bug. Is this a bug?

Let me push this up to top again.
