The follow-up PR of https://github.com/Qix-/color-string/pull/76.

Did you notice that your projects has no references from other projects? GitHub cannot recognize the issue and PR links from yours. I've reported this issue to them: https://github.com/orgs/community/discussions/170750 🤦

Huh that's really weird. That's definitely worked before :| It might be because I have a grandfathered-in username with a dangling hyphen.

Hmm, it may be a cache issue? The CI fails after I revert the version.
nvm, I mis-typed the version number.

BTW, should we treat the current HWB output of .hwb().string() as a bug?

As the https://developer.mozilla.org/en-US/docs/Web/CSS/color_value/hwb documentation states, there should be no comma between the HWB parameters.

Or adding a new option flag to allow users to strip the comma?

[Qix-]

Yep seems so.

From https://drafts.csswg.org/css-color/#the-hwb-notation:

There is no Web compatibility issue with hwb, which is new in this level of the specification, and so hwb() does not support a legacy color syntax that separates all of its arguments with commas. Using commas inside hwb() is an error.

Emphasis mine.

@Qix- Should I update the .hwb().string() logic in the PR?

[Qix-]

Yes please that'd be very helpful 🙏🏻

@Qix- I've created a pull request to https://github.com/Qix-/color-string/pull/84 to fix the output format.
