Point colors default to black even though they are provided

Hi,

I noticed an issue after switching to the latest regl-scatterplot release. I notice some strange behaviour with point colors in certain cases.
The issue is triggered when I make 2 or more draw calls in succession, with the 2nd draw having the same first k colors as the first but extra colors thereafter. The remaining colors seem to be get colored as black.
I made a reproducible e.g. here, after you click the button there are 2 draw calls, the 2nd one should have an additional orange point but we get a black instead.

I did not have this issue with version 1.12.

Thanks for making so many new features available, really appreciate your work on this great library.

Best

Thanks for reporting and sorry about the glitch. It looks like the second color texture doesn't get uploaded properly. I'll investigate.
