[css3-regions] flow-into on inline or table-cell

The spec says 'flow-into' applies to anything. If applied to inline elements, what are expectations for flow behavior - are inline elements concatenated in lines, or should there be an anonymous block for each one?

Also, if elements in flow are of the kind that normally require fixup (like table-cell), is it expected that fixup is performed separately in the composed flow, or would such elements change effective display type (e.g. table-cell would become a block unless it somehow ends up in a table-row)?
