Ordinal numbers plural selector are not working

[8549]

The third example on the Fluent docs page "Selectors" does not work with grammY's i18n plugin.

MWE

# en.ftl
request-success = You are { NUMBER($queueLength, type:"ordinal") ->
  [1] next
  [one] the {$queueLength}st
  [two] the {$queueLength}nd
  [few] the {$queueLength}rd
  *[other] the {$queueLength}th
} in queue!

// main.ts
import { load } from "dotenv";
import { Bot, Context } from "grammy";
import { I18n, I18nFlavor } from "@grammyjs/i18n";

const env = await load();

const i18n = new I18n({
  defaultLocale: "it",
  directory: "locales",
});

const bot = new Bot<Context & I18nFlavor>(env["BOT_TOKEN"]);
bot.use(i18n);
bot.command(
  "example",
  (ctx) => ctx.reply(ctx.t("request-success", { queueLength: 2 })),
);
bot.start();

Expected result

Bot replies with "You are 2nd in queue!"

Actual result

Bot replies with "Your are 2th in queue!"
Same result if queueLength = 3.
