<meta name="assert" content="Fixed positioned boxes in a line-clamp container are hidden if and only if their fixed positioning containing block precedes or contains the clamp point. In this case, the containing block is the line-clamp container, so the fixed-pos gets shown, even if its static position is after the clamp point.">
