Reviewed by Tyler Wilcock.
AccessibilityObject::lineRangeForPosition() walks forward from the
position and, when the text between two adjacent positions contains a
newline, returns the range including it. This needs to be updated to
take into account synthesized newlines at the end for layout purposes
that aren't really part of the content.
