[UX sort of bug] The auto-completion started by a colon is rather confusing

[ell1e]

Your use case

What would you like to do?

The auto-completion started by a colon is rather confusing and unlike any other messengers I use. The expected behavior is that if I type :jo and press tab immediately, I get :joy:.

This is what actually happens:

1. If I do this too fast, nothing. The completion popup shows up late but my tab press that already happened is ignored. This is very frustrating

2. If there is a user around, even though users are even shown with @ and not : (and in all other messengers I use, you need an @ to start a user auto completion), and the user has a name that starts similarly, I might suddenly auto-complete to the user.

3. Only if none of the above two fail, I get what I actually intended.

This makes feel element feel unreliable and moody, and most importantly, it messes up muscle memory. The emoji auto completion shouldn't be timing dependent and predictable, these seem to be broken by the strange throwing in of users and the delayed popping up - which I'm suspecting might also be due to the users being loaded or queried from the server?

TL;DR: please make the emoji auto complete not fail if I type too fast and not auto-complete the users if I typed : and not @ (so I clearly want an emoji and not a user, one would think?)

Why would you like to do it?

The changes suggested above would be nice so using emojis in element isn't so frustrating and weird

How would you like to achieve it?

See above

Have you considered any alternatives?

The other messengers work fine with this. Also, I guess I could type really slowly, but I'm hoping that nobody is seriously suggesting this as a good soluton
