Setting the page margins to outside of the print range, and maximizing the header/footer margins, then switching between the tabs sets the fields to negative values. Applying the changes pushes the content off the page.

Using the replication steps, this issue can be repeated with the Footer tab (instead of Header), and you can use the right margin instead of the left as well (although the content will be pushed off to the other side of the page).

I’d consider this an edge case as it would be very unlikely that anyone with good intentions would go anywhere near those margin values.

Steps to Reproduce:
1. Open new LibreOffice document
2. Click on Format > Page … > Page tab
3. Set the Left Margin value to 0
4. Click on the Header tab
5. When prompted about margin being out of print range, click yes.
6. Toggle Header on.
7. Set the Left Margin to 9999 (anything beyond the current margin limit)
8. Click on the Page tab.
9. See the value for Left Margin is now negative.
10. Click on Header tab again.
11. See Left Margin now negative, and preview shows content area far off the page.
12. Click OK (to accept edits and close the window).
13. Try to type things in header or main content area. No text appears, but character count increases.

Actual Results:
Margins automatically got set to negative values. Text does not appear anywhere, but word count increases as you type.

Expected Results:
Margins should never be negative and cause text to appear outside of view.
