This patch fixes bidi reordering sometimes confused by empty
inline boxes.

These items do not have resolved bidi levels. Before this
patch, |NGInlineLayoutAlgorithm| reordered ignoring such
items. This patch changes it to assign bidi levels to such
items by copying from adjacent items and let reordering to
handle them.
