Selection at the beginning of paragraphs is broken on IE9 and IE8

[Jakub Ś]

I have found it when checking #9093

To reproduce:

1. Insert below code and switch to WYSIWYG

   <p>aaa</p>
   <p>bbb</p>
   <p>ccc</p>
   

2. Try to select 'bbb' but start your selection a little bit to the left of 'bbb' like shown in picture.
3. Once bbb is selected press Enter key

Result: new line is inserted above 'aaa'

Alternative step 3:

3. Once bbb is selected, press Link button and insert a link. Note that the link is inserted in the wrong place (at the end of contents).
   

The same thing happens with inline styles - they are added at the end of content. You can inspect it only with developer tools.

This issue has only been reproducible in IE8 and IE9 from CKEditor 3.6.3

Reproducible from rev. [7374]

It's caused by the revert of one of our ​previous wysiwygarea hack, considering that [7374] cannot coexist with it, we'd rather leave this one right now, which is relatively an small case.
