Missing presence updates after service restart

Issue description

Hello and thank you for this project.

Using discord.js we created a bot connected to server which has over 1.2M members.
In this server we try to listen to all presence updates:

import { Client, Partials } from 'discord.js';

const bot = new Client({
  intents: 257,
  partials: [
    Partials.Channel,
    Partials.GuildMember,
    Partials.GuildScheduledEvent,
    Partials.Message,
    Partials.Reaction,
    Partials.ThreadMember,
    Partials.User,
  ],
});

bot.on('presenceUpdate', handlePresenceUpdate);

bot.on('raw', async (event: { t: string; d: any }) => {
  if (event.t === 'PRESENCE_UPDATE') {
    await handlePresenceUpdateRaw();
  }
});

@ApmMonitor('handlePresenceUpdate', 0.01) // only 1% of calls is recorded via APM
function handlePresenceUpdate() {
}

@ApmMonitor('handlePresenceUpdateRawViaDiscordJS', 0.01) // only 1% of calls is recorded via APM
function handlePresenceUpdateRaw() {
}

It looks like discord.js does not emit all presenceUpdate events at the beginning, even when all partials are turned on because when we start/restart the service, the amount of handlePresenceUpdateRawViaDiscordJS calls is much higher than handlePresenceUpdate calls.

For comparison see handlePresenceUpdateRawViaDiscordJS calls before/after restart:

And handlePresenceUpdate calls during the same period:

Is it possible that discord.js tries to cache some additional resource first before it emits presenceUpdate event?
