<title>CSS Overflow: abspos in line-clamp in zero-sized div</title>

<meta name="assert" content="Absolute positioned boxes inside a line-clamp container are shown if their containing block is after the clamp point. This test specifically tests that this is the case where the container is an other-wise empty, zero-height div, which does fit before the clamp point.">
