IE11 throw Invalid State error with this particular Blob construction

I have this code to save an excel using Blob

//Stream of data as res
var dataView = new DataView(res);
var blob = new Blob([dataView], {type: 'application/vnd.ms-excel'});

But in IE only the third line throw Invalid State Error even though in the document, it is fully supported

It seems that the issue pertains to IE. Uint8Array can be used in the constructor instead.

To convert a DataView to a equivalent Uint8Array:

var u8arr = new Uint8Array(dataView.buffer, dataView.byteOffset, dataView.byteLength);

Write a function to replace all DataView objects in the array passed to new Blob. Or see the polyfill here.
