Landscape div creates unwanted blank page at end of Word document

Bug description

When using the .landscape div to create landscape-oriented pages in Word output, an extra blank page is automatically added at the end of the document.

Steps to reproduce

Reproducible Example:

Save the following code block as test.qmd

---
title: "Landscape Test"
format: docx
---

## Regular Content

This is some regular portrait content.

::: {.landscape}

## Landscape Section

```{r}
library(flextable)
ft <- flextable(mtcars[1:10, 1:8])
ft
```

:::

Run:

quarto render test.qmd -t docx

Open test.docx to view in MS Word.

Actual behavior

An extra blank page (page 3 in my case) appears after the landscape section. This blank page contains only the section break required for the landscape formatting.

Screenshots:

Expected behavior

The document should end immediately after the landscape section without any trailing blank pages.

Reproduce the issue with the provided test.qmd and quarto render test.qmd -t docx, then inspect how the landscape div and section breaks are represented in the generated Word document. The work is done when the landscape section renders without a trailing blank page while preserving the required orientation change.
