IE11 regular pasting doesn't work

1. Open an editor instance with new pastefromword implementation in IE11.
2. Set the content using source button to the following:

<h1>Hello world!</h1>

<ol>
	<li>dsa</li>
</ol>

<p>I&#39;m an instance of <a href="http://ckeditor.com">CKEditor</a>.</p>

1. Press ctrl + x.
2. Press ctrl + v.

Expected result

Content gets pasted.

Actual result

Nothing happens.

Important notes

It happens only on Windows 7 IE11 - I've tested it with Windows 10 IE11 and it's fine there.

Also the bug comes 100% from new PFW, as if you disable the plugin it works OK.

Pushed possible solution to ​branch:t/16593.

I've pushed simple fix earlier in master. To ensure that it works as expected I've uploaded a manual test to be included during the release. See ​branch:t/16593b. R?

LGTM merged with ​git:7d1ebbe.

Turned out that the issue was still present on major branch. Pushed new solution to ​branch:t/16593c.

This solution is a little bit dirty, but it should do.

I doubt there exists a general way to detect whether something was pasted from Word.

LGTM.

Yes, I found that mso-list is the main tell here. There's one global regexp match on each CKEDITOR.cleanWord call for performance reason, you could do it for each ol / ul on innerHTML - but then the performance would be hurt, so that's the compromise.

I think that we could look at dissolveList and make it a little smarter in upcoming releases, so it handles regular lists gracefully.

Fixed with ​git:a00236b.
