Takayoshi Kochi 2015-05-18 07:34:21 UTC According to the current spec, http://w3c.github.io/webcomponents/spec/shadow/#active-element Document.activeElement returns "adjusted" element, i.e. when the real focused element is within a shadow tree, it returns the top-most shadow host in the Document treescope. 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. --- Reply to this email directly or view it on GitHub: https://github.com/w3c/webcomponents/issues/104
