Delayed color change for invalid colors

[xavfernandez]

Expected behavior

I would expect the invalid colors to be constant.

Current behavior

When using invalid colors like rgba(267,292,60,0.2) or rgba(560,60,60,1) (with 267 & 560 outside the expected 0-255 range) the color is not "stable" on hover transition and changes twice.

Reproducible sample

Optional extra steps/info to reproduce

• Hover on first bar "A" and exit: the bar A will update its color twice
• Hover on second bar "B": the bar B will update its color twice during hover

Context

Since this happens with invalid colors the behavior is clearly unspecified but the current behavior is unexpected/surprising (and did not happen with v2.9.3).

v3.7.1

Why would you try to pass invalid colors to the chart in the first place?

That was not intentional.

@kurkle should this be moved to https://github.com/kurkle/color ?

Maybe, I'll debug this.

Ok, looks like this is an issue with the color lib. Transferring.

Edit: can't transfer. Anyway, it will be fixed in @kurkle/color v0.2.0

Seems it can only be transferred to another repo in the org.
