LibWeb: Fix floats y offset calculation

Browse source 
There is a difference in y offset position calculation for floats when
LineBuilder provides final y position while for blocks it needs to be
adjusted by `y_offset`. This difference already accounted in floating
box position calculation and this patch also makes it accounted in check
whether a floating boxes on the same line intersect between each other.
