<p>1x4 with orthogonal items. <br>All items share 'first-row' Baseline Context. No item shares any column-like Baseline Context.<br>All the items are orthogonal to the row-axis, so they don't participate in the row-like Baseline Context; since no items shares column-like Baseline context, neither 'justify-self' or 'align-self' should apply.</p>
