Rationale for going from "standard mode" to "strict"?

Should not need the <double> here.

Doesn’t seem like we need an if here. Just a return.

Looks better on a single line?

How do you know you found all the places that depend on the old range?

Oh, wait, I guess those are two names for the same sort of thing. Somehow I thought "standard" was the non-strict.

strictCSSParserContext() is just a CSSParserContext with HTMLStandardMode. 

const CSSParserContext& strictCSSParserContext()
{
    static MainThreadNeverDestroyed<CSSParserContext> strictContext(HTMLStandardMode);
    return strictContext;
}

So it should behave the same.

Good point. Fixed.

Searched for all uses of HSLA in the code. Since you explicit conversion is needed it's pretty easy to find them all.

Thanks for the review.

You can't use strictCSSParserContext in parseColorWorkerSafe. See Bug 222156.
