Paste from word plugin - problem with numbered lists

[yuri.pavlov]

The bug is reproducible under IE 11. When the user copies (even a single) line from a numbered list, like :

1. First
2. Second

the result we see inside the CK window is (CK demo used) :

1. <>

So the entire internal text is missing, it is replaced by <>.

What I found is that the text coming into plugin is like :

<ol style=\"list-style-type: decimal; direction: ltr;\">
<li style='color: red; font-family: \"Calibri\",\"sans-serif\"; font-size: 11pt; font-style: normal; font-weight: normal;'>
<p style='color: rgb(0, 0, 0); font-family: \"Calibri\",\"sans-serif\"; font-size: 11pt; font-style: normal; font-weight: normal; margin-top: 0in; margin-bottom: 0pt; mso-list: l0 level1 lfo1;'>
	<span style=\"color: red; mso-ansi-language: EN-US;\">First</span>
</p></li>

........

It is gradually transformed to :

"<ol><li cke:indent=\"1\" cke:listtype=\"ol\" cke:list-style-type=\"\">
<cke:li cke:reset=\"1\" cke:indent=\"1\" cke:listsymbol=\"First\"></cke:li></li></ol>"

Which then leads to the behavior I described.

Problem can be reproduced only in IE11 from CKEditor 4.3.

Before version 4.3 (but we didn't have support for IE11 then) list was pasted as set of paragraphs in IE11
