Bug report

Reproduction of the problem

Behavior A is reproducible in this DOJO

Behavior B is reproducible in this DOJO. This is the same as A, but some rows are removed from the first table

Behavior A-2 is reproducible in this DOJO. This is the same as A, but with 1 large row instead of many rows.

Behavior B-2 is reproducible in this DOJO. This is the same as A-2, but rows from letter 'h' are removed from the first table

1. Load the page, pdf file should download when loaded

Current behavior

1. A: The second table header is duplicated without any actual table rows.
2. A: The first table's last rows got slightly cut off from the first page.
3. B: The second header is duplicated, but on the first page, without any actual data rows.
4. A-2: The first table header is duplicated.
5. B-2: The second header is duplicated, but on the first page, probably without any actual data rows. Note that the header is not inspectable as a textLayer node in Firefox's built-in pdf viewer
6. B-2: The first table's header is now not duplicated. (The first page of B1's pdf is not present anymore)

Expected/desired behavior

1. No table header should be present without actual table rows.
2. The first table's last row should appear on the second page as it doesn't fit on the first page.
3. The table header should only be rendered at the end of a page if it fits with at least one actual table row.
4. No table header should be present without actual table rows.
5. The table header should only be rendered at the end of a page if it fits with at least one actual table row.
