I had this same issue.

 

Demo page also did not work.

 

I applied the change to the code you recommended.

 

Now, it works, in IE too ... BUT:

 

 - Only for on file at a time.  Multi-file selection will not work. 

 

- After selecting the file, the progress panel formatting is wrong ... it shows "in-line" in the render after the button.

 

It does work, tho.

 

Note that this only effects IE.  EVERYTHING works (multi-file and rendering) correctly in other browsers.
