Fundamentally, because if the spec didn't say this, then having floats intersect with something that's scrollable would require the browser to rewrap (around intruding floats) the contents of the scrollable element every time it scrolls. This is technically what CSS 2.0 required, but it was never implemented, and it would have been a huge problem for speed of scrolling. -David -- 𝄞 L.
