Problem:
In a fresh devel environment, the following error is shown in the browser console:
Uncaught TypeError: Jed is not a constructor

When I attempted to turn on assets_debug in foreman/config/settings.yaml to get a better idea of the error, the problem went away. I hope this is helpful to someone else one day!
