[css] Prefer usage of RenderStyle::textDecorationsInEffect() when rendering

• Component: CSS
• Status: RESOLVED FIXED

[Bruno Abinader (history only)]

WebKit currently has a proprietary CSS property '-webkit-text-decorations-in-effect', which as far as I've studied on the code and tested, is only used internally as part of the 'text-decoration' CSS property implementation (as up to CSS spec 2.1). Inside WebCore/rendering, there are mixed usage of both RenderStyle::textDecoration() and RenderStyle::textDecorationsInEffect(). To avoid a possible breach in terms of data redundancy, prefer usage of RenderStyle::textDecorationsInEffect() sounds more correct, after render style adjustments.

Hmm, seems that I completely misunderstoond the concept here, thus I haven't attached this part of the patch into bug 90959... removing review request.

Actually not quite fully invalid :) I just found a breach while implementing patch for -webkit-text-decoration-color (bug 91638) where textDecorationsInEffect() is saner than textDecoration() usage: inside RenderObject::getTextDecorationColors, where colors for underline, overline and linethrough are obtained. However, there is no sense in having a separate patch for this change, which makes more sense to be part of that patch.
