Source/WebCore:
In the css3-text spec (http://www.w3.org/TR/css3-text/#bidi-linebox):
The start and end edges of a line box are determined by the inline
base direction of the line box. In most cases, this is given by
its containing block's computed ‘direction’. However if its
containing block has ‘unicode-bidi: plaintext’, the inline base
direction the line box must be determined by the base direction of
the bidi paragraph to which it belongs: that is, the bidi
paragraph for which the line box holds content.
This patch just implements the behavior described above modifying
updateLogicalWidthForAlignment and setting the bidi level of the
RootInlineBox.
