Add support for type="module" script tags so we can use ES6 import/export #174
Description
I have a commit providing this functionality on my local fork. Happy to make the pull request; your docs say to ask first.
Tell us about the issue you are experiencing
import / export syntax in javascript files listed in assets.js fails because they are loaded without the type="module" attribute
What behaviour would you expect?
the choice to separately list javascript assets that should be loaded with the type="module" attribute
How can this issue be replicated?
include an ES6 import in a javascript file listed in assets.js.
Screenshots / Screencast
