<pre>REGRESSION (<a href="http://trac.webkit.org/projects/webkit/changeset/202472">r202472</a>): Data Detection overwrites existing links in detected ranges
https://bugs.webkit.org/show_bug.cgi?id=170365
<rdar://problem/29205721>
Reviewed by Tim Horton.
Source/WebCore:
<a href="http://trac.webkit.org/projects/webkit/changeset/202472">r202472</a> changed the node traversal in searchForLinkRemovingExistingDDLinks() to only
consider nodes that are descendants of startNode, but we need to traverse all nodes between
startNode and endNode to find existing non-DD links.
As a result, we'd add a Data Detector link to the following snippet and make the original
links un-clickable:
<a href='#'>tomorrow</a> <a href='#'>night</a>
Fix this by not specifying a stayWithin node when calling NodeTraversal::next(). The loop
will terminate when we reach endNode.
Updated WebKit2.DataDetectionReferenceDate API test.
* editing/cocoa/DataDetection.mm:
(WebCore::searchForLinkRemovingExistingDDLinks):
Tools:
* TestWebKitAPI/Tests/WebKit2Cocoa/DataDetection.mm:
(expectLinkCount): Changed to only query links with the x-apple-data-detectors attribute.
(TEST): Re-enabled the test, which now passes.</pre>
