Apps seems to fail on IE9:
SCRIPT65535: Invalid calling Object
ie.js, line 40 character 48

I can confirm this. The error seems to be in the minification of the outerHTML hack. I tried the original version from this gist which works fine, but the minified version throws an error.

Remove outerHTML and createElementNS shims. Fixes #339
Not needed anymore, since we don't support <IE9
