Reviewed by Alan Baradlay.
Merge - https://src.chromium.org/viewvc/blink?view=revision&revision=180488 &
https://chromium.googlesource.com/chromium/src.git/+/116b2f293d0c16017e63e45cc9a97ee5bfa9b161
Per http://www.w3.org/TR/CSS2/visudet.html#abs-non-replaced-width if an
absolute positioned box's 'left' and 'right' values are both auto then it
should position itself as though it is a normal flow box in relation to its
containing block. Where the positioned box's container is a rel-positioned
inline we should disregard any offset created by that inline when
positioning the positioned box's layer.
This bug was spotted during a discussion at
http://lists.w3.org/Archives/Public/www-style/2014Jul/0549.html. The tests
are drawn from that discussion and attributed appropriately.
NOTE - Webkit was not adding any absolute positioned element with a
counter offset similar to Blink but the commit was referenced to update the
comment.
