Same code with a script src tag works fine.

Nice One!  However, I'm still seeing the issue in the latest pull (unless yarn (me) is being stupid).


Yeah ESLint supports ES6 Modules. Standard is a good preset (https://standardjs.com/) and there is alway Semi-standard if you really insist on semicolons!

UPDATE: This could be because I'm using the preview release builds from the repo. Not sure if these are updated every merge.
