Main Problem: Section Header with IsSubsequentPagesOnly = true is included in document for all sections on all pages except the first one. (Should not be included on first page of each section.)
Another Problem: Header not shown on random pages. (Example: If you hard-code randomSeed = 1670481123; below then section 2 page 3 does not include header.)
