IE11 does support Blob URLs but not for type text/html and also not for usage in an iframe: caniuse.com/#feat=bloburls
Just putting this here so others don't waste time trying this solution as an alternative for srcDoc in IE11.
Try this one in IE11 codepen.io/grimen/pen/lBuiG/

Thank you very very much, Hendrik! Indeed, text/html cannot be used in IE11
