I was able to reproduce a regression (in 1.4) for `number-sections` YAML option for websites and books[^1].

```bash
quarto create-project --type website:blog website
echo "    number-sections: true" >> website/_quarto.yml
echo -e "\n\n## Heading 1\n\n### Heading 2\n\n## Heading 3" >> website/about.qmd 
quarto preview website
```

| 1.3 | 1.4 |
