Summary Adjusting relatedTarget can be much faster and more accurate

Once we have O(1) access to shadowRoot, we can: 1) Easily determine whether we even need to walk anything. 2) Use scopes to check whether we need to adjust relatedTarget. See http://dev.w3.org/2006/xbl2/#the-mouseover-and-mouseout-events for more details. 3) Use scope chain to walk more quickly.

I think we already have O(1) access to shadowRoot. Let me rewrite adjust relatedTarget code.

Thank you for the info. SVG still looks blocking as you said. :( (In reply to comment #2) > (In reply to comment #1) > > I think we already have O(1) access to shadowRoot. Let me rewrite adjust relatedTarget code. > > SVG is still blocking you :(.

Nevermind. We don't support those two events. https://bugs.webkit.org/show_bug.cgi?id=18930
