We can't get text-align right during the initial table reflow because the
inline-size within which the cell content is to be aligned is not yet known
(it'll come from the block-size we compute for the parent row).
So to deal with this, we record during tableRowFrame reflow whether any
cells with orthogonal writing mode were present; and if so, at the end of
the row reflow, we make another pass over the orthogonal cells and reflow
them to properly align their content within the computed cell size.
