OGVPlayer: Refused to get unsafe header "Content-Range"

[Mesoptier]

As the title says, when loading a sample with useOgvFallback enabled, I get this error in my console:

Refused to get unsafe header "Content-Range"

As far as I can tell, this is a CORS-related issue. I might also be the first person to have this issue, since I'm running the soundboard frontend locally but using the production API. I guess that when they're running on the same origin, there's no CORS issues.

I think it could be fixed by adding this header: Access-Control-Expose-Headers: Content-Range.

See also this line in stream-file (the library used by ogv.js): https://github.com/brion/stream-file/blob/d1b41ca2992b908d8910d5389b6a663146d5d5b3/src/backend/backend.js#L30

I labelled it with soundboard-3.0, but just realized that the same issue might exist for the main branch.

Hmm. I've tested OGV.js plenty from local to real API and on Safari as well and never ran into this somehow. I'll try to reproduce.

Also I have some concerns with the 3.0 tag. I get the reference to editor 3.0, but the soundboard's already passed v3.0 a while ago. Shouldn't it be v4.0? And wouldn't this cause PTSS for you every time you see the tag? =O
