Reviewed by Antti Koivisto.

This patch aligns WebKit with Gecko / Firefox and Blink / Chromium.

Merge: https://src.chromium.org/viewvc/blink?view=revision&revision=199132

Outermost SVG roots should be consider atomic inline-level, and hence
text decorations should not propagate into them from the outside.

* Source/WebCore/style/StyleAdjuster.cpp:
(isOutermostSVGElement): Add new static function
(shouldInheritTextDecorationsInEffect): Update as per commit
* LayoutTests/svg/text/text-decoration-propagation.html: Add Test Case
