title: Issues with Developer Tools (IE 11) - "Error: Object doesn't support property or method 'addEventListener'"
body: <p>If I try to open developer tools in IE11, it re-opens the page, zoomed in (and losing any focus/selected element). If I then close the developer tools, it throws a "Error: Object doesn't support property or method 'addEventListener'" error, and the space at the bottom of the page where the dev tools were is unpainted, but empty.</p>
