[css-box-4] margin-trim auto-margins needs more clarification wrt. fallback alignment. #11397
Description
Consider:
<!DOCTYPE html>
<div style="display: flex; margin-trim: block; align-items: end; width: 100px; border: solid 2px; height: 100px;">
<div style="background: lime; margin: auto;">hi</div>
<div style="background: lime; margin: auto;">hi</div>
</div>
Presuming that auto margins are trimmed, should the alignment of the items be the start or the end?
