IE: collapsed selection and inline style exchange wrapping inline element.

[Jakub Ś]

Problem can be reproduced from CKEditor 4.0 (works fine in 4.0 beta) in IE9-11.

To reproduce:

1. Create a paragraph and enter text, say "This is plain text"
2. Select whole paragraph and apply Bold
3. Click once inside paragraph and try to apply any inline style from styles dropdown.

Result: In IE, the inline style gets applied to whole paragraph even when text was not selected after clicking once.

NOTE: This issue has been reported on our support channel. User claims that the range.collapsed property returns false in IE whereas in e.g Chrome it returns true.
