spree/backend.js being required in spree_i18n.js

[fabiode]

Hello!

Is there a reason for spree/backend.js being required in spree_i18n.js file? This causes some conflicting behaviors when you want to require the backend.js file in a custom project. If you try to require in your project's vendor/javascripts/spree/backend/all.js, Sprockets raises Sprockets::CircularDependencyError.

But if you remove the //= require spree/backend from your vendor/javascripts/spree/backend/all.js file, it does not raises the error, but the content of spree/backend is not required into all.js, and even if it was required correctly, it's kind of strange making spree_i18n, an external gem, being responsible for requiring it.
