deferReply() not working properly in Bun

[Mahonzu]

Which package is this bug report for?

discord.js

Issue description

Steps to reproduce:

1. Replace Bun.env.TOKEN with your bot's token
2. bun run sample.ts
3. use /ping on the bot
4. See "<application> is thinking..." forever
   From my testing it either awaits deferReply forever, or throws both The reply to this interaction has not been sent or deferred. and Interaction has already been acknowledged.
   Works completely fine with node and deno

Code sample

import { Client, Events, MessageFlags } from "discord.js"; 
const client = new Client({ intents: [] });

const sleep = (ms:number) => {
    return new Promise(resolve => setTimeout(resolve, ms));
}

client.once(Events.ClientReady, (readyClient) => {
	console.log(`Ready! Logged in as ${readyClient.user.tag}`);
});
client.on(Events.InteractionCreate, async (interaction) => {
	if (!interaction.isChatInputCommand()) return;
	
	if (interaction.commandName == "ping") {
		await interaction.deferReply({ flags: MessageFlags.Ephemeral });
		await sleep(1000)
		await interaction.editReply({ content: "pong" });
	}
});

client.login(Bun.env.TOKEN);
