When using autocomplete options, let user stay in option when selecting an autocompleted value

[kingmigdor]

At mobile it's possible to automatically stay in the autocomplete, even when a choice has been clicked. This can be used if the bot needs to suggest more options, like if we have a /docs command it could suggest the attributes of it for example.
I also don't think that both clients should behave different in this case, because it could limit developers when they have ideas of making autocompleted options.

My problem is that I don't get the choice before the user entered the command when they clicked a choice on desktop, but on mobile I still get the value. I did some hacky stuff in my code and made the second autocompleted option behave on the first option. I don't know how to explain, but when I selected a game in the first option, in the second option there should only be the accounts of that game I chose in the first one. This would be the use-case I have here, and it works well on mobile, but not on desktop.
