<title>CSS Overflow: line-clamp hidden floats should count as ink overflow</title>

<meta name="assert" content="Any overflowing content hidden from paint by line-clamp is treated as ink overflow, including floats, and therefore doesn't cause the scrollable overflow rectangle to grow. Meanwhile, non-hidden floats count as scrollable overflow.">
