I’m running into this error here on meta. I can’t reproduce it in my development environment, but I always get it here on meta.
[https://github.com/discourse/discourse/blob/master/app/assets/javascripts/discourse/lib/autocomplete.js.es6#L60-L62](https://github.com/discourse/discourse/blob/master/app/assets/javascripts/discourse/lib/autocomplete.js.es6#L60-L62)
Steps to reproduce:
- Click “New Topic” and leave the editor open
- Go to my user preferences

Can confirm. I am, however, able to close the error and interact with user preferences as expected, even with the post editor open.

I get the same bug just when editing one of the “About the XYZ Category” topics. No need to navigate to user prefs.

Should this really be an alert? Or can it be a console.log entry?
I’m noticing it appearing on the Poll UI Plugin because I embed the editor in a Modal, while it is still open in on the topic/create new topic.
It initially took me by surprise because I wasn’t sure what “only supporting one matcher at the moment” meant, it would be nice if this were 1) more specific, such as, “AutoComplete: only supporting one matcher in an editor at the moment” and 2) a console.log statement, since it isn’t really breaking anything (from what I can tell).

On the upside this did catch a pretty ugly bug… nonetheless fixed per
