IE 6&7 Getting handlers when we navigate to first paragraph(non-editable) in editor body.

[Satya Minnekanti]

To reproduce the defect:

1. Open CK Editor and create some paragraphs of text(both editable and non editable) & make first paragraph non-editable or copy the below code and paste it is source view.

<p contenteditable="false">
	first non editable paragraph.</p>
<p> first editable paragraph. </p>
<p contenteditable="false">
	second non editable paragraph.</p>
<p> second editable paragraph. </p>

2. Go back to Rich text keep the cursor at end of last paragrAph and navigate to top paragraph using arrow keys.

Issue: we are getting handlers when we go to the Top Paragraph(non-editable) and we can't come out of it.

Only happening in IE6 & 7

I have attached a screenshot of the error.

This has occurred first in version 3.2.1 and then from version 3.3.2 till current.

In versions 3.2.2 - 3.3.1 navigating with arrows caused insertion of empty paragraph at the top.

In versions 3.0.2 - 3.2 the first non-editable paragraph was deleted when navigating with arrows.

I cannot reproduce it on IE8 on CKeditor 4.3.
