[clarkdo]

Types of changes

• Bug fix (a non-breaking change which fixes an issue)
• New feature (a non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)

Description

In production, App.js js is concatenated by webpack, so there is no App.js module info
in client.manifest.json.

Way to preload fonts if anyone is interested in verifying the issue:

    bundleRenderer: {
      shouldPreload: (file, type) => {
        return ['script', 'style', 'font'].includes(type)
      }
    }

• All new and existing tests are passing.
