Setting "error" in filterwarnings in `pyproject.toml` silences specific warning

Hello! :wave:

Specifying "error" at the top of the filterwarnings list in pyproject.toml silences a warning, while I expected it to be raised as an error. It raised the warning for other warnings, I don't understand why it doesn't work for that particular warning. Could you give me some instructions as to how to track down the problem? I already disabled every plugin I could. I am aware that this is not a minimal reproducible example as I figure that this a bug in my configuration.

By commenting "error" in filterwarnings, I do get the warning.

Uncommenting it just silences it instead of raising it.
