Description Emilio Cobos Álvarez 2017-07-04 21:19:54 PDT
bool isItalic() const
    {
        if (!obliqueValue) {
            auto valueID = fontStyleValue->valueID();
            return valueID == CSSValueItalic || CSSValueOblique;
        }
        return obliqueValue->value<float>(CSSPrimitiveValue::CSS_DEG) >= static_cast<float>(italicValue());
    }

Note how "|| CSSValueOblique" makes the first return always return true.

I'm not familiar with this code, so I'm not sure how to best test it.

Happy to fix it with indications on how to test it. I've CCd the original patch author and reviewer so you can take a look (and fix) if you want to.

Should this be called isItalicOrOblique?

This is the ugliest <script> I've seen in a long time :)
