Strange suggestion from suspicious_operation_groupings

Lint name: suspicious_operation_groupings

I tried this code:

    pub fn set_scheme(&mut self, scheme: &str) -> Result<(), ()> {
        let mut parser = Parser::for_setter(String::new());
        let remaining = parser.parse_scheme(parser::Input::new(scheme))?;
        let new_scheme_type = SchemeType::from(&parser.serialization);
        let old_scheme_type = SchemeType::from(self.scheme());
        // If url’s scheme is a special scheme and buffer is not a special scheme, then return.
        if (new_scheme_type.is_special() && !old_scheme_type.is_special()) ||
            // If url’s scheme is not a special scheme and buffer is a special scheme, then return.
            (!new_scheme_type.is_special() && old_scheme_type.is_special()) ||
            // If url includes credentials or has a non-null port, and buffer is "file", then return.
            // If url’s scheme is "file" and its host is an empty host or null, then return.
            (new_scheme_type.is_file() && self.has_authority())
        {
            return Err(());
        }

I expected to see this happen: accepted without warnings.

Instead, this happened:

error: This sequence of operators looks suspiciously like a bug.
