CORS settings not being applied to Spaces?

I’m trying to upload to Spaces via fineuploader, which is a Javascript based file upload library. Since it’s uploading from the browser it needs CORS settings applied.

I set up a Spaces called “cors-test” in the ny3 region. I set the CORS headers to the following:


However when the library sends the preflight OPTIONS request to Spaces, the Access-Control-* headers are not applied, as can be seen in the following screenshot.


What’s wrong here?
