## Bug Report **Problematic behavior** When using `h4` (to `h6`) tags in a document, the outline seems to consider them as higher level (`h1`?) **Expected behavior/code** `h4` to `h6` tags should be ignored in the document outline or properly indented. **Steps to Reproduce** Markdown content: ```md ## Sub-Section 1 ### Sub-subsection 1.1 #### sub-sub-subsection 1.1.1 ## Sub-Section 2 ### Sub-subsection 2.1 #### sub-sub-subsection 2.1.1 ``` **Environment** - Docs version: latest? - Instance url: https://docs.numerique.gouv.fr **Additional context/Screenshots** Preview 🖼️ <img width="1012" height="477" alt="Image" src="https://github.com/user-attachments/assets/e3db4ff0-a428-4c4a-a7f1-9fd30a5638e8" />
