IndexSizeError when printing report in IE 11

[hungvuong1003]

To export PowerBI report in client site, I use 'print' function in powerbi-client javascript lib. This function works well on Chrome, Firefox.
But when testing it in IE11, I meet these error messages:
'ReferenceError: 'Promise' is undefined'
'IndexSizeError'
Regarding to Promise issue, It is a ES6 syntax, I can use polyfill library to fix it. But I cannot find a solution to fix the 'IndexSizeError' issue. Try print report on Powerbi Playground in IE 11, it also meets the same issue 'IndexSizeError' (https://microsoft.github.io/PowerBI-JavaScript/demo/v2-demo/index.html#).

Any ideas? Thanks in advance.
