1x4 with parallel and orthogonal items. Items orthogonal to the baseline-axis will use a synthesized baseline (border-box 'under' edge).
All items share 'first-row' Baseline Context. No item shares any column-like Baseline Context.
Items participate in both, column and row baseline, but since they only share a row-like Baseline Context only 'aling-self' (column baseline-axis) should apply.
The Baseline Alignment may increase size contribution of some items.
