Firebase how to allow "Range" Header

I set my CORS header for Firebase Storage with the following cors.json and gsutil

[
  {
    "origin": ["*"],
    "method": ["GET", "OPTIONS"],
    "responseHeader": ["Range", "Content-Type"],
    "maxAgeSeconds": 3600
  }
]

But I still get this error:

MLHttpRequest cannot load http://url_to.csv. Request header field Range is not allowed by Access-Control-Allow-Headers in preflight response.

I also tried replacing Range with Content-Range but it didn't have any effect.
