`Uncaught (in promise) TypeError: e.map is not a function in d.editor`

edit : re-writing now that I have found the cause

After some testing, it appears that this error happens when the **emoji\_autocomplete\_min\_chars** site setting is set to a value different than 0.  
The error will occur each time we type a character after a colon. Also, the colon must be the first character of the line or have a space character before.

If **emoji\_autocomplete\_min\_chars** is set to 3, the error will appear for the first 3 characters typed before the emoji selector is shown.

I don’t know if it affects anything or causes unwanted behavior that I can’t see behind the curtains.

edit: 2.9.0.beta3 and beta2, tried in [safe mode](https://meta.discourse.org/t/53504?silent=true) 🙂
