webpush modifies the vapid_claims parameter

I have an object in my Django config for vapid claims and I’m using it in the webpush method.

I couldn’t realize why after sending push messages on Firefox I was constantly getting “unauthorized registration” errors on Chrome, until I saw that the object passed as vapid_claims parameter gets modified from something like this:

{
    'sub': 'mailto:<my_email>'
}

to this :

{
    'aud': 'https://updates.push.services.mozilla.com',
    'exp': '1508309139',
    'sub': 'mailto:<my_email>'
}

I tried passing every time a new object and everything works fine, but now I’m wondering, is this expected behavior, and am I supposed to store that modified object?
