* LayoutTests/accessibility/mac/ruby-hierarchy-roles-expected.txt:
* LayoutTests/accessibility/mac/ruby-hierarchy-roles.html:

Update the test for the new ruby hierarchy.
Blockify by setting position:absolute.

* LayoutTests/platform/mac-wk1/TestExpectations:

Disable for now in WK1 because the setting leaks accross tests.

* Source/WebCore/accessibility/AccessibilityRenderObject.cpp:
(WebCore::AccessibilityRenderObject::computeAccessibilityIsIgnored const):
(WebCore::AccessibilityRenderObject::determineAccessibilityRole):

Return the roles.

* Source/WebCore/rendering/updating/RenderTreeBuilderRuby.cpp:
(WebCore::RenderTreeBuilder::Ruby::findOrCreateParentForStyleBasedRubyChild):

Return the existing anonymous ruby box for a ruby-block parent if there is one.
