Widget not deleted properly

I'm using the widget inside a component that's shown or hidden in a form, and I found out that when I hide the container component, the recaptcha is still shows, but in the top-left corner, above anything else.
I solved this setting the restamp="true" in the container component, and modifying the detached method as follows:

  detached: function() {
    // TODO: remove event listener
    this.container.remove();
  },

Do you think it can be the correct approach?
Thanks

Hi, the initial problem is the recaptcha doesn't work inside shadow dom, so it is appended to the body in case it has a shadow root parent. So when you hide your form, the widget might no longer be inside.

You can use the hidden property that handles the work of hiding the in-body widget, ex:

<template is="dom-if" if="[[condition]]">
  <google-recaptcha hidden="[[!condition]]" ... ></google-recaptcha>
  ...
</template>

And you're right, the container has to be removed when detached, submit a PR if you want ;)

Oops remove() is not supported on IE11. Maybe something like

this.container && Polymer.dom(Polymer.dom(this.container).parentNode).removeChild(this.container);

or after all it only has to be remove when in-body

this.inBody && this.container && document.body.removeChild(this.container);

I'm not sure, I did'nt test that code
