in ES6, in this case (arrow function):

const modal = () => {
    $templates.append(tmpl('glossary', data));
}

this in case is undefined but window is working. @ShinyChang

You seem to have superfluous control characters in your commit, which break the StandardJS linting tests.

Could you also provide a failing test case?
The code example you provide doesn't seem to be the source of your issue as far as I understand it.

I assume this could be closed, right?

@vinyll yes, thanks.
