"Bidi isolation is forced on all internal ruby boxes and the ruby container: 
the normal and embed
values of unicode-bidi compute to isolate, and bidi-override computes to 
isolate-override."

(WebCore::RenderTreeBuilder::Ruby::findOrCreateParentForStyleBasedRubyChild):

Set unicode-bidi::isolate for the anonymous base.

* Source/WebCore/style/StyleAdjuster.cpp:
(WebCore::Style::isRubyContainerOrInternalRubyBox):
(WebCore::Style::adjustUnicodeBidiForRuby):
(WebCore::Style::Adjuster::adjust const):

Adjust unicode-bidi for container and annotation boxes per spec.
