           Summary: [Shadow]: ShadowRoot needs to support elementFromPoint
           Product: WebAppsWG
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Component Model
        AssignedTo: dglazkov@chromium.org
        ReportedBy: dfreedm@chromium.org

document.elementFromPoint(x,y) returns a reference to the element at (x,y).
However, the children of a ShadowRoot, and the ShadowRoot itself, will return
the host of the ShadowRoot. This leaves no way to find an shadow'd element at
(x,y) without manual hitbox testing in javascript.

Note: "light dom" elements from insertion points work correctly with
document.elementFromPoint
