The real focused element can be retrieved by recursively applying .activeElement against shadowRoots on the way, but it may be convenient to have a way to directly retrieve the element from Document. One use case is for accessibility plugins; when a web app is provided as one custom element (e.g. <topeka-app> at https://polymer-topeka.appspot.com/), Document.activeElement always points to <topeka-app>, which does not make much sense for accessibility plugins. It may be also necessary to have another type of event than "focus", which fires when Document.activeElement changes. 120649 1 kochi 2015-06-02 02:26:32 +0000 Moved to GitHub issue. https://github.com/w3c/webcomponents/issues/104
