We have this :

### What changes are you suggesting?

Fix the **Markdown** issues in the **French**-translated and **Spanish**-translated versions of the article "[Searching issues and pull requests](https://docs.github.com/en/search-github/searching-on-github/searching-issues-and-pull-requests)", and potentially other languages.

I would have opened a PR, but according to your [translation contribution guidelines](https://github-docs-43.mintlify.app/contributing/translations) this content is not open to direct community contributions.

See the **Additional information** section for more details.

### Additional information

I initially noticed the issue in the French version. I then observed similar problems in other locales, but I haven’t checked all of them. For example, the Spanish version of the article also shows broken Markdown: [Spanish version](https://docs.github.com/es/search-github/searching-on-github/searching-issues-and-pull-requests).

Start with the French and Spanish article links in the issue and compare their rendered Markdown with the English article. Check whether other locales show the same problem; done means the affected translated pages render well-formed Markdown without breaking the article content.
