           Summary: [Shadow]: Stop 'load' and 'error' events at shadow
                    boundaries
           Product: WebAppsWG
           Version: unspecified
          Platform: PC
        OS/Version: Windows NT
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Component Model

Various HTML elements fire load and error events, but typically only once. 

Given the event retargetting behavior in Shadow DOM, when elements within a
shadow subtree fire a load or error event (e.g. IMG), that event will propagate
out and appear to be an event on the shadow host itself. This will happen for
each piece of shadow content which fires such an event, giving the impression
that the shadow host has reached a 'load' or 'error' state (or both!) multiple
times.

To avoid this, the load and error events should be added to the list of events
which are stopped at the nearest shadow boundary.
