Great catch + great test.

I'll change the loop to an enumerated loop for landing. I think that will make such cases clearer.

> Source/WebCore/css/CSSSelector.cpp:347
> -    const AtomicString& lastArgument = argumentList.last();
> -    for (const AtomicString argument : argumentList) {
> +    const AtomicString* lastArgument = &argumentList.last();
> +    for (const AtomicString& argument : argumentList) {
>          str.append(argument);
> -        if (argument != lastArgument)
> +        if (&argument != lastArgument)
>              str.appendLiteral(", ");
>      }

Great catch, I did not think of this while reviewing.
