Invalid delimiter found

Using this dataset: https://media.githubusercontent.com/media/datablist/sample-csv-files/main/files/organizations/organizations-100000.csv

The sniffer finds the delimiter : while it is clearly ,.

Code (similar to the example found in this repo):

extern crate csv_sniffer;

use std::path::Path;

use csv_sniffer::{SampleSize, Sniffer};

fn main() {
    let data_filepath = Path::new(file!())
        .parent()
        .unwrap()
        .join("../data.csv");
    let dialect = Sniffer::new()
        .sample_size(SampleSize::All)
        .sniff_path(data_filepath)
        .unwrap();
    println!("{:#?}", dialect);
}

output:

Metadata {
    dialect: Dialect {
        delimiter: ':',
        header: Header {
            has_header_row: true,
            num_preamble_rows: 1,
        },
        quote: None,
        flexible: false,
    },
    num_fields: 2,
    types: [
        Text,
        Text,
    ],
}

Is this a known issue?

ps: with another sample_size it also gives the wrong delimiter.
