------- Additional Comments from roseN <rosen.dash at motorola.com>
This patch addresses folllowing two issues:

 1. In case of using CSS pseudo elements before/after with content attribute
containing single character at the start/end of text and there
    is no text in parent node, when we try to move cursor beyond the inserted
character using left/right arrow key, the page freezes
    falling into an infinite loop.

 2. When these elements try to insert some text between a text line, navigation
by right arrow key is prohibited.

For better understanding please use the following test case.
