Iframe fails to load for Pencilcode Gym on IE 11

Thanks for the bug report. Does ie11 have a way of debugging the Dom tree?
Is there an iframe pointing at frame.pencilcode.net?

On IE 11 on Windows 8, the iframe for frame.pencilcode.net is empty in on
all pages, and I see no errors on the Developer Tools console. In addition,
all network requests succeeded, according to the Developer Tools network
monitor, but there is no request going to frame.pencilcode.net. Maybe
it's something wrong with the browser iframe security or the URL being too
long? Works on the same computer using Google Chrome.

Some more notes, after some investigation: Frank is right that it's due to the URL being too long.

Test with the example here http://david.pencilcode.net/edit/testing/embed.html - when the url is short enough, it works. When it's too long, IE fails to load the frame silently.

Need to come up with a way of initializing the embedded frame without using the url hash part to embed the source code.

I've pushed a change to the codegym project that fixes this problem by using postMessage instead of URLs to initialize the frame. A little slower, but it works on IE11:
