Mentions tooltip stuck when typed too quickly about github-writer HOT 3 CLOSED

GitHub RTE doesn't contain any code that controls the display of the mentions list, so this is definitely an upstream issue to be reported to CKEditor 5.

I had some intuition when trying to reproduce the problem which pointed me to the right direction... it's all about the speed of the feed filter function. If the function resolves after the user already moved out of the mentions typing, the list will show up with delay and stay stuck there.

For GitHub RTE, the list of issues comes from a XHR request made for the first time the mentions are used. Therefore, if the download and processing of the list meets a super fast typer, like you @mlewand, it can blow up.

To test it, I've messed up with this line of the filter code, changing it to the following:

setTimeout( () => {
	resolve( results );
}, 1000 );

It gave me 1s to move out of the mention typing and the issue is then easily reproducible.
