test case

Possibly from http://trac.webkit.org/changeset/156355

Sample URL: on bugzilla.mozilla.org
https://bugzilla.mozilla.org/show_bug.cgi?id=468568

Try to click on an attachment link.

In the attached test case: links inside the cyan block (parent table) are unclickable. If I remove the ‘box-shadow’ on the inner table (left column), magically the link start to work.

I don’t think that is the only trigger. Margin: auto is (possibly) needed, more?

This page: http://www.atimes.com also exhibits the issue (try the article links or the navigation column, light blue on the left), but individual pages work correctly.

Looks like I lost a ! here:

-            if (child->isBox() && !toRenderBox(child)->hasSelfPaintingLayer()) {
-                LayoutPoint childPoint = flipForWritingModeForChild(toRenderBox(child), adjustedLocation);
-                if (child->nodeAtPoint(request, result, locationInContainer, childPoint, action)) {
+            if (row->hasSelfPaintingLayer()) {

I think this might be it.
