[BUG] Forgot password screen loading overlay stuck on

[BenSturmfels]

Forgot password screen at /users/password/new:

There's a JavaScript error in the console:

Uncaught ReferenceError: I18n is not defined

Caused by this code:

<script>
    I18n = I18n || {}
    I18n.defaultLocale = "en"
    I18n.locale = "en"
</script>

I'm sure this is super simple to fix, I think I'll look at it in the next few days
