The issue is on how IE treats hash. It doesn't default to empty string like the other browsers, it defaults to '#'. Also rather than setting hash, you should set location for reliability in IE.

hash = window.location.hash !== '' ? window.location.hash: '#about';

becomes

hash = window.location.hash;
if (hash !== '' || hash !== '#') {
   hash = '#about';
   window.location = hash;
}

The markup was not rendering because it was not resetting the hash on entry and giving an error message that '#' was not a valid selector for the filter.
