The site complete fails to load if a single js file can't be loaded from a single plugin. We put in some work previously to sandbox a single plugin failure so it wouldn't bring down the site, but it doesn't appear we handled this "missing" js file case. We should probably have an issue to fix it as I'm sure files will be occasionally forgotten or renamed, etc.
