title: return the active language of the Google Translate Web Element
body: <p>I am using a dynamic shoppingcart running on javascript and cookies. I want to enable a language switcher for it, to switch some words (strings) that I have translated manually, using the hooks provided:
  <a href="https://github.com/wojodesign/simplecart-js/issues/95#issuecomment-1316249" rel="nofollow">simplecart</a>.
  I also will be using the Google Translate Web Element to machine translate the static content of the site.<br>
  Now rather then ending up with 2 dropdowns: one to switch the dynamic content, and one to switch the static, I would like to 'listen' to the GTWE, so my own translation switches to the selected, or auto detected language.
  How do I tap into the GTWE to get its current language to use in JS?
  Or is it not possible and should I be asking how to command the GTWE with my own dropdown for my translations.(the other way around)</p>
