<p>4x1 with parallel and orthogonal items. <br>No item shares any row-like Baseline Context. All items share 'first-column' Baseline Context.<br>Only the parallel items participate in baseline alignment in the column-like Baseline Context; since no item shares row-like Baseline Context, only 'justify-self' (row baseline-axis) should apply.<br>The Baseline Alignment may increase size contribution of some items.</p>
