End of the range is enlarged randomly.

[Piotr Jasiun]

After call range.enlarge( CKEDITOR.ENLARGE_ELEMENT ); in some cases <\p> tag is inside enlarged range (dt/core/dom/enlarge.html 'test space 9', currently in ​git:t/10778)

<p>foo <i><b>[bar]</b></i> </p> ->
<p>foo [<i><b>bar</b></i> </p>]

and in some it is not (dt/core/dom/enlarge.html test_enlarge_element5):

<p>Test <b><i>[Enlarge</i> this]</b></p> ->
<p>Test [<b><i>Enlarge</i> this</b>]</p>
