Description Ryosuke Niwa 2013-07-17 11:03:24 PDT

Consider merging https://chromium.googlesource.com/chromium/blink/+/1b5e6d8d09e59fb25df0319e48af4fb05493856a

In TreeScope::elementFromPoint,
 - nodeFromPoint can return a Text node which is a child of a ShadowRoot. We
   should search ancestors of the ShadowRoot in this case.
 - ancestorInThisScope returns this ShadowRoot if |this| is passed. We should
   handle such case.

I don't think the problem happens in WebKit because of no Shadow DOM API.

Comment 2 Ryosuke Niwa 2016-04-11 01:50:32 PDT

We should check if this is still broken or not.
