This also breaks the signature code block highlighting.\n\n### To Reproduce\n\nset the following in mkdocs.yml\n``` yml\nplugins:\n  - mkdocstrings:\n      handlers:\n        python:\n          options:\n            separate_signature: true\n\nmarkdown_extensions:\n  - pymdownx.highlight:\n      auto_title: true\n```\n\nView any generated documentation\n\n### Expected behavior\ninside div `language-python doc-signature highlight`, the span containing Python should be class `filename`, not `nf`.\n\n### Environment information\n\n- __System__: Linux-5.15.167.4-microsoft-standard-WSL2-x86_64-with-glibc2.35\n- __Python__: cpython 3.10.12 (/usr/bin/python)\n- __Environment variables__:\n- __Installed packages__:\n  - `mkdocstrings-python` v1.16.10\n\n### Additional context\nPretty sure this is due to this commit: https://github.com/mkdocstrings/python/commit/7f956868f93a766346455fedb296c26787894d5c\nThe regex `\u003cspan class=\"[a-z]+\">` matches `\u003cspan class=\"filename\">`. You could use `\u003cspan class=\"[a-z]{1,2}\">` instead potentially?\n","author":{"url":"https://github.com/nataziel","@type":"Person","name":"nataziel"},"datePublished":"2025-05-30T05:17:52Z","url":"https://github.com/mkdocstrings/python/issues/281"}
