----------------------------------------
Summary: Stream download iframe may not exist in DOM at time of
removal

... IE seems to have a problem with the fallback code for removing the download
iframe from the body. If the iframe is successfully removed by the callback of
the iframe.onload handler, the stream.onend callback encounters an error
because the iframe is no longer attached. A check for iframe's parentElement
being defined is a workaround:
{code:javascript}
stream.onend = function downloadComplete() {
$window.setTimeout(function cleanupIframe() {
if (iframe.parentElement) {
document.body.removeChild(iframe);
}
}, DOWNLOAD_CLEANUP_WAIT);
};
{code}

In both the iframe's onload handler and the stream's onend handler, the iframe
itself should only be removed from the DOM if it is actually present.
