[Request] Force caching mentioned users on loaded messages.

It would be awesome to have tagged user id resolved(cached) and shown properly (as intended)
within an Embed.

Instead of it showing an <@ID-HERE> as mentioned user (also unclickable)

 here's an example: https://i.snag.gy/gye43P.jpg

Or refresh that message when the caching is done.

Would be an awesome tweak for client-end users that can't quite cache quickly.

Only if it's possible!
