LibWeb: Allow scrolling overflowed content with the mouse wheel :^)
This is rather crude, but you can now use the mouse wheel to scroll up and down in block-level boxes with clipped overflowing content. There's no limit to how far you can scroll in either direction, since we don't yet track how much overflow there is. But it's a start. :^)
