* IE 11 has a fantastic bug where it will produce two trailing BR elements to iframe bodies when
* the iframe is hidden by display: none on a parent container. The DOM is actually out of sync
* with innerHTML in this case. It's like IE adds shadow DOM BR elements that appears on innerHTML
* but not as the lastChild of the body. So this fix simply removes the last two
* BR elements at the end of the document.
*
* Example of what happens: <body>text</body> becomes <body>text<br><br></body>
