Error in browser console when using hashtag autocomplete in the composer: undefined generateIconHTML

[zogstrip]

@Moin

In full safe mode (no themes and no plugins), as soon as I use # in the composer, this error appears:
Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'generateIconHTML')

This one will be fixed by

If I use safe mode only for themes, so plugins are active, the error above does not appear when I use the hashtag autocomplete. But after I select a category using #, it triggers this error instead:
[autocomplete] handleKeyup: TypeError: this.options.dataSource is not a function

That one I’m having trouble reproducing
