Function focus() failed under IE if some of the HTML elements has style with specified width or height attributes

[Andrey]

Steps to reproduce:

This issue is easy to reproduce by using api.html CKEditor sample:

• run api.html sample on IE (any version)
• Start debugging
• Set editor content to:

<div style="width: 300px; height: 300px;">

<span class="text" style="font-family: Arial; font-size: 10pt;">CKEditor</span>

</div>

• select text
• right click and select "Copy" Now you will get error: ckeditor.js, line 265 character 107; SCRIPT16389: Incorrect function.

Without debugging you will just fail to do any actions that can change focus: like copy/paste using popup menu, change font name or font size by using font list boxes from toolbar.
