Polymer in Widget

Hello, the plugin work perfectly well for all polymer elements but it would be good if polymer elements where available in widget. They work in widget only if you already used the same element in a [poly] shortcode in the same page where the widget is displayed but it’s not a good solution knowing that we can’t edit some pages ( like 404 or search page ) or if we don’t want to see this element in the page content. I already tried to manually import the element in the page’s code with the import link provided by Polymer but it didn’t work. Thanks.
I used Polymer Components 1.1.2 and wordpress 3.9.2.
