<meta name=assert content="Flex items with layout containment are treated as having no baseline, for that reason their baseline is synthesized from the flex item's border box when they're baseline aligned.">
<style>
#flex {
display: inline-flex;
align-items: baseline;
background: red;
}
canvas {
background: green;
width: 50px;

}
#item {
contain: layout;
color: transparent;
background: green;
width: 50px;
height: 100px;
}
</style>
<p>Test passes if there is a filled green square and <strong>no red</strong>.</p>
