Bug report - you can view the issue here: http://jsfiddle.net/bradhogan1983/sxwge12m/
When using the iframe option and clicking a link to open the modal, the modal opens instantly, but the iframe takes a second to load and while loading the modal container is just a small empty box. This happens on your demo as well as my local dev site. I'll also attach a screenshot of what I'm seeing on my dev site.
Thanks!
