Mesh won't show in multiple Mesh3D plot

Hi all,

I’ve been testing out plotting simple meshes using Mesh3D in both JavaScript and R. I’m interested in plotting multiple separate meshes onto the same 3D axes. So far I’ve just been hardcoding coordinates, which form planes, which I pass in as additional mesh objects. This seems to work fine for certain data. However, in some cases the a mesh won’t render, even though the coordinates are very simple. Initially I started in R and then changed to JS and found the same issue.

Here is the example. 3 planes should be rendered, 2 are parallel and one is orthogonal. The orthogonal one won’t show unless I change it tilt very slightly (by modifying the x coordinates).

Can anyone tell me if I’m missing something or this is a bug?

Thanks for the report.
