When I try to embed an image with a relative path from a markdown file that exists in a subdirectory as shown below, docx output on Windows seems to fail. (`quarto render --to docx`)
It was not a problem on Linux, so it may be related to the path separator character.

```sh
$ tree .
.
├── img.png
├── _quarto.yml
└── sub
    └── test.md
```

test.md's content

```md
---
title: "quarto-test"
---

## Quarto

![](../img.png)
```
