Fix SCRIPT16389: Unspecified error. IE <=11 on page refresh

[kirylkastko]

The author of this PR #230 didn't fix a conflict. I decided to create a new a new PR. Really need this fix to be merged.

Same question as before – is there any way you could make add a regression test?

[kirylkastko]

I'll try.

@kirillkostko Can you at least give me any more information as to why IE11 throws here? Is it throwing when we access window.history inside an <iframe>? Or window.history.state?

[kirylkastko]

It happened when I started my React app, not inside iframe. When we access window.history.state, IE throws this error.

@mjackson Hi, have you found something?

[laurel-taylor]

I'm also getting this error inside a react app with IE11..

As a workaround, I've put the following in the html page, and it seems to be working:

<!--[if IE 11]>
 <script>
  window.history.state = {};
 </script>
<![endif]-->

@mjackson, @taion angular also wraps accessing window.history.state for the same reasons

Just FYI everyone, this fix was released in version 2.1.2.
