The root cause is a <details> element, which is implemented a shadow host, but may have a <summary> element as an immediate child. There is no shadow root between them. Please see a ChangeLog for the details. 451019 4 hayato 2011-08-15 03:29:03 -0700 Note that this patch is a quick fix for crash, restoring the original behavior of <details> element. In this case, <details> and <summary> elements, we should not stop event dispatching at <details> element . Although <details> element is implemented as a shadow host, but this is not a 'component' from the view of users. 'mouseover' event which happens at <summary> element should not stop at <details> element and should bubble up. I'll file another bug.
