<p>A (deprecated) flexbox shouldn't allow its items to form a continuation chain, since a
    flexbox isn't a block flow (block container).</p>
<p>There should be a square below.</p>
<div style="font:20px/1 Ahem; display:-webkit-box; -webkit-box-pack:justify;">
    <span>
        xxx
        <div>xxx</div>
        xxx
    </span>
</div>
