MODELTRANSLATION_AUTO_POPULATE = True has no effect with non-default language

Django==2.2.13

MODELTRANSLATION_AUTO_POPULATE = True

If my current language is different from default language, and I create an object, it doesn't populate the default field value.

For example, I have below in my settings:

LANGUAGES = (
('en', gettext_noop('English')),
('ar', gettext_noop('Arabic')),
)

If I go the create page, and select "ar" as my current language. Create the model object. I then change my language to default language "en". The en field doesn't get populated. Whereas, if its the other way round, and I create an object with "en" selected, then it populates "ar" field properly. Is this how it is designed? Or am I missing something with auto-populate function?

Looks like this is how it designed.

Take a look at modeltranslation/translator.py and try to find a bug.

In my case, I'm not set MODELTRANSLATION_AUTO_POPULATE but it still auto copy all translated field to default field although I have provided value for default fields.
