Before this change, we'd always insert one line box fragment, even when a float was taking up too much space on the line, and the fragment didn't actually fit. We now perform line breaks until we have enough space between floats. This fixes many page layouts where we'd previously see small fragments of inline content outside the right edge of the containing block.
