[Webkit]: Cursor jumping to start of editor body when we press enter after last list item in outer list

[Satya Minnekanti]

To reproduce the defect:

1. Open any sample in nightly build

2. Type some text & create a simple 2-level Numbered/Bulleted list below it

3. Keep cursor at end of last list item in outer Numbered/Bulleted list and press Enter

Expected Result: A new list item created in outer list and cursor stays after the new Number/Bullet that was created

Actual Result: A new list item created in outer list but cursor jumping to start of editor body.

This is happening in all Webkit browsers (Chrome, Safari & Opera)

I think it is a DUP of #10247.
