Looks mostly good, but needs to be merged with my similar patch in 89556, and we need to decide if the returned targetNode should be the shadow-element or the shadow-ancestor.

> Source/WebCore/page/EventHandler.cpp:2493
> +    bool success = findBestClickableCandidate(targetNode, targetPoint, touchCenter, touchRect, *nodeList.get());
> +    if (success && targetNode)
> +        targetNode = targetNode->shadowAncestorNode();
> +    return success;

I am unsure about this change. For point-adjustment it doesn't matter, but we want to fix the problem of performing unnecesary later hit-testing later and just use the found target node. If we return a shadowAncestorNode instead of the shadow element, we would have the same problem again then.

Was erring on the side of caution.  Without this node adjustment, we introduce a regression in touchadjustment/html_label.html.  I see that you have addressed the change in behavior in your patch for 89556.  Happy to back out the changes to event handler and land the test portion of the patch after your patch, or alternatively it might make sense to push this change in first and then back out the node adjustment in your more detailed patch.  Option 3 is to merge the nested shadow node test into your patch.

Reopening to attach new patch.

Added FIXME to remove need for shadowAncestorNode.

This is supported in HitTestResult side. The BlackBerry port, for example, only works with shadow content, if they have a media element (<video> or <audio>) as ancestor.

The bug 69556 does not seem related. Maybe wrong bug ID?

Dom => DOM

nit: space before/after "/"

Wrong ID.  Corrected to 89556 (Touch adjustment does not target shadow DOM elements).

>> LayoutTests/touchadjustment/nested-shadow-node.html:37
>> +    function addShadowDom() {
> 
> Dom => DOM

Done.

>> LayoutTests/touchadjustment/nested-shadow-node.html:81
>> +        var top = touchY - padding/2;
> 
> nit: space before/after "/"

Done.

Even though we plan to land it is a two patches, I would still prefer if you closed this bug as a duplicated, and landed the patch under the original bug. They are the same bug-report, and the title is more accurate in the older bug.

[Kevin Ellis]

Test added to 89556.
