Before anyone say anything like that IE is crap, other web apps loading and working fine in IE 11.
Console message:

Internet Explorer 11 on Windows 7 64bit.
A horse can carry a little bomb… this means every bomb have to be designed to be carried by horses?
Maybe it should work/be solved, but anyway, IE is not dead? It will be (possibly) replaced by Spartan (and maybe it is not just IE 12 with a new name) 
I didn’t know that IE will be replaced by a “new” browser 
But I don’t think it dead anyway, seems like it will affect only Windows 10 and maybe Windows 8 later but I’m pretty confident Windows 7 going to keep IE 11 because as far as I know Win 7 stopped receiving new “features” it going to get only security updates form now on until 2020 or something and so IE 11 but no new features and apps anymore, so I don’t expect Spartan on Windows 7 but maybe this time will be different and IE 11 along with Win 7 will be dead before end of support as Win 10 looks pretty promising to be honest
