Google Places API details language not working

I am working on a bilingual project and started to use Google Places API Webservices. I started using the Place Autocomplete API which works great.

I can do this query in both fr and en and will get different description results:

https://maps.googleapis.com/maps/api/place/autocomplete/json?key=<insert_key_here>&types=geocode&language=<insert_language_here>&input=144

English result:

  "description": "14458 Gouin Boulevard West, QC, Canada",
  "id": "33dcffeeb88b48fa5c1d0ec4e6e54469d05f5d1e",
  "place_id": "ChIJk0pAHBM7yUwRt0WIxWRe1ic",

French result:

  "description": "14458 Boulevard Gouin Ouest, QC, Canada",
  "id": "33dcffeeb88b48fa5c1d0ec4e6e54469d05f5d1e",
  "place_id": "ChIJk0pAHBM7yUwRt0WIxWRe1ic",

The ids are exactly the same but the text is localized which is the expected result. Now when I try to get the same result using the Place Details API, the language parameter doesn't seem to have any impact. I know that the documentation mentions results should be returned, if possible. but given I know it is possible, is this behavior by design or some sort of bug?

Here is an example of an english details query using the previous example place_id which returns the result in french:

https://maps.googleapis.com/maps/api/place/details/json?key=<insert_key_here>&placeid=ChIJk0pAHBM7yUwRt0WIxWRe1ic&language=en

    "long_name": "Boulevard Gouin Ouest",
