<h3>Log Message</h3>
<pre>[GTK] Layout test accessibility/aria-hidden-false-works-in-subtrees.html fails after <a href="http://trac.webkit.org/projects/webkit/changeset/184890">r184890</a>
https://bugs.webkit.org/show_bug.cgi?id=146718
<rdar://problem/21722487>
Reviewed by Joanmarie Diggs.
Source/WebCore:
Allow to get the text under element for nodes hidden in DOM but explicitly exposed to accessibility with
aria-hidden="false".
Fixes: accessibility/aria-hidden-false-works-in-subtrees.html
* accessibility/AccessibilityNodeObject.cpp:
(WebCore::AccessibilityNodeObject::textUnderElement const):
* accessibility/atk/WebKitAccessible.cpp:
(roleIsTextType): Also consider ApplicationGroup role as text elements, so that <div>text</div> is equivalent to
<div role="roup">test</div>.
LayoutTests:
Update test to ATK behavior, rebaseline it and remove the expectations.
