<meta name="assert" content="When computing flex container's overflow area, its padding rect is added to flex item's margin-box, not flex item's overflow rect. This test verifies that last part; making sure it's not mistakenly added to the flex container's overflow rect.">

overflow: auto;
width: 100px;
height: 100px;
background: red;
