Django 1.11: How to include a translation file in JavaScriptCatalog?

Question

Django

File with translation from locale\ru\LC_MESSAGES to JavaScriptCatalog is not picked up.
settings.py

LANGUAGE_CODE = 'en-us'
TIME_ZONE = 'UTC'
USE_I18N = True
USE_L10N = True
USE_TZ = True

LANGUAGES = [
    ('ru', _('Russian')),
    ('en', _('English')),
]
LOCALE_PATHS = (
    os.path.join(BASE_DIR, 'locale'),
)

urls.py

urlpatterns += i18n_patterns(
url(r'^jsi18n/$', JavaScriptCatalog.as_view(), name='javascript-catalog'),
)

django-admin makemessages -l ru
Editing the translation in locale\ru\LC_MESSAGES\django.po

django-admin makemessages -d djangojs -l ru
django-admin compilemessages

The file locale\ru\LC_MESSAGES\django.po is created
And at 127.0.0.1:8000/ru/jsi18n there is only a basic translation that does not include the translation from locale\ru\LC_MESSAGES\django.po

Asked this question on stackoverflow, django forum - nobody knows. Filed it as a bug to the django developers, but was sent to tinker with the tests
There is a ​specific test for that in the Django test suite. It may be the test is missing something, but you should explore that yourself and explain it if it's the case.
