<h3>Log Message</h3>
<pre>Merge <a href="http://trac.webkit.org/projects/webkit/changeset/174074">r174074</a> - AX: in an aria-labelledby computation, do not traverse into elements whose nameFrom value does not include 'contents'
https://bugs.webkit.org/show_bug.cgi?id=136714
Reviewed by Darin Adler.
Source/WebCore:
There are certain ARIA elements that tell us we should not query their children when determining the name of the object.
Those ones have the "nameFrom" property set to "author" instead of "contents." WebKit needs to honor that status.
Test: accessibility/aria-namefrom-author.html
Modified: accessibility/aria-labelledby-with-descendants.html
* accessibility/AccessibilityNodeObject.cpp:
(WebCore::shouldUseAccessiblityObjectInnerText):
(WebCore::shouldAddSpaceBeforeAppendingNextElement):
(WebCore::appendNameToStringBuilder):
(WebCore::AccessibilityNodeObject::textUnderElement):
(WebCore::accessibleNameForNode):
(WebCore::AccessibilityNodeObject::accessibilityDescriptionForElements):
* accessibility/AccessibilityObject.cpp:
(WebCore::AccessibilityObject::accessibleNameDerivesFromContent):
(WebCore::initializeRoleMap):
* accessibility/AccessibilityObject.h:
