The type for Response.headers was previously typed as Dict[str, str], but that is not completely correct. Header values can also be a list of strings, e.g. for multiple Set-Cookie headers. See #1214 when this feature was introduced.
The wrong type definition was introduced in afd23d7d729f8383033fe3851bc1de5effd1f22f.
