FF : we can't navigate up the read-only blocks using UP arrow key

[satya]

To reproduce the defect

1. Copy the following code snippet

   <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. Keep cursor at end of last paragraph and use UP arrow key to navigate to the other editable paragraph.

Expected Result:

we should be able to navigate to the other paragraph using UP arrow key.

Actual Result:

No matter how many no of times we press the arrow key cursor still remains at the beginning of last paragraph.
