Surface colorscale error for colorscales of length >=256

[jonmmease]

It seems that there is a breakdown in the colorscale handling for the surface trace when the colorscale definition has length >= 256.

CodePen: https://codepen.io/jonmmease/pen/OGLOYK

For colorscale of length 255, things work as expected:

For colorscale of length 256, the colorbar is displayed properly but the surface is not rendered and there is a console error:

Error: ... map requires nshades to be at least size 256

If there is a hardware need for a colorscale length limit it would be great if this could be increased from 255 to 256 because that's a relatively common length for colorscales specified in libraries like matplotlib and colorcet.

Thanks!

No problem. First we wanted to include that in 1.46.0.
But it would be fixed in 1.46.1.
