`::: {.landscape}` div overrides footer content in `reference-doc`

Bug description

I'm using Quarto to render a MS Word document (DOCX) and have modified the reference document to include page numbers in the footer (no other changes). When I use the {.landscape} class within a div (documented here), the newly added section overrides the footer content, and only displays in the very last section of the document. Below are screenshots for the actual and expected DOCX outputs.

Unfortunately, this behavior makes Quarto unusable for my requirements. I really hope I'm just doing something wrong or there is a simple fix, because I would love to use Quarto if possible.

Steps to reproduce

1. Follow the instruction here to create a custom DOCX reference doc.

2. Add page numbers to the reference doc, save, and close.

3. Create a QMD file from the code below.

---
format: 
    docx: 
        reference-doc: custom-reference.docx
jupyter: python3
---

Portrait

::: { .landscape }

Landscape

:::

4. Run the following command.

quarto render x.qmd

Actual behavior

Footer page number only appear in the last section.

Expected behavior

Footer page numbers appear in all sections, not just the last one.

Reproduce the issue with x.qmd, custom-reference.docx, and quarto render x.qmd, using the documented landscape div and page-number footer. Trace the DOCX section and footer handling responsible for the generated output, then verify that the page numbers appear in every section rather than only the last one.
