<span class="quote">> Assuming that we want to silently ignore the single size, I think the
> cleanest way to write the sourceSize function would be to have it return
> Optional<CSSParser::SourceSize> and return no source size at all when the
> value is invalid rather than instead using a size with a CSS_UNKNOWN
> primitive value in it.
>
> The call site in CSSGrammar.y.in could just not append a size in that case.
>
> But I am not sure what the desired behavior is in this error case.</span ></pre>
