nat::wire3d is plotting polygons when there should only be triangles - not a problem with rgl::wire3d #511

Hello,

I am using wire3d to plot a mesh3d object with the plotly backend. I noticed that there are polygons on my mesh. The data is only triangles and when I check with RGL, I also only see triangles:

RGL:

rgl::wire3d(mesh)
image

nat: 

options(nat.plotengine = 'plotly')
wire3d(mesh,
       add = FALSE
)
image

What I do notice is that I scroll around the RGL plot, sometimes vertices seem to disappear and it looks like a polygon exists where there isn't one due to the lighting effects.
