So the reason we get the current bogus result is that overflow:hidden are block-formatting contexts (BFC) and in paginated mode they are implemented as block frames with NS_BLOCK_CLIP_PAGINATED_OVERFLOW to do the clipping. When we have a child float that doesn't fit, we split it and currently we report that as Overflow-Incomplete (which is correct for a normal block, but not a BFC) which leads to creating an overflow-container continuation which has zero size which we then clip. We should report it as Incomplete instead, except if we already are an overflow-container.
