scatter3d marker size has different meanings when specified as a single value vs as an array.

[ksze]

When using Scatter3D, the marker size has very different meanings when specified as a single value vs when specified as an array.

To reproduce:

1. Visit this codepen: https://codepen.io/k_sze/pen/MOqZpY
2. In the codepen console, run restyle1() and restyle2();
3. Watch the points getting very different sizes.

restyle1() specifies the sizes of the markers as an array filled with the integer 12;
restyle2() specifies the sizes of the markers as a single value of 12.

Ha good catch. Those array-item values should be multiplied by 2 here.

Fixing this old (pre-open-source) bug would arguably break many existing graphs. So I think it would be best to wait for v2, unless someone can convince us otherwise.

Hi - this issue has been sitting for a while, so as part of our effort to tidy up our public repositories I'm going to close it. If it's still a concern, we'd be grateful if you could open a new issue (with a short reproducible example if appropriate) so that we can add it to our stack. Cheers - @gvwilson
