I like the "top of page" rule. It would make no sense to me if clearance could be applied to part of a block.

I also agree that use cases with overlapping floats can only occur from bad design or misuse of content, so it doesn't matter all that much what the result is...

I agree with performing layout on a per-page basis, with the implications of boxes possibly changing widths across pages (or a region break).

But I'm not sure about the "top of page" rule. Is it more important to place a continuation at the top of a page than to honor its layout constraints?
I've attached a screenshot showing fixed-width left and right floats getting squeezed, overlapping or just staggering without the "top of page" rule. I'm not sure I see a big advantage to either of the first two if the fixed width was the author's intent.


Allowing continuations to use normal layout without a top-of-page rule seems easier to implement and easier to explain. I think in most intentional situations the continuations will naturally fit at the top of the page anyway. Can we leave out this rule?

Thanks,

Alan
