Basically -- I have one 'header' (really just a standard <h4>) which is generated in-line / in-body, and I have a Prince repeating-header -- when the <h4> happens to overlap with the Prince repeating header, how do I ensure that the <h4> is the one that is "on top", rather than the Prince header?

Why does it overlap? Is it overflowing the page margin?

Don't injected 'prince-flow' elements always overlap something else? It is not overlapping the page margin.

The page margin is supposed to be set large enough to contain the margin box content.
