title: api.instagram CORB network error because of jsonp response header with `Content-Type: application/json`
body: <p>I'm using <a href="https://github.com/camsong/fetch-jsonp" rel="nofollow noreferrer">fetch-jsonp</a> to fetch <code>https://api.instagram.com/oembed/?url=&lt;embedUrl&gt;</code> to use the <code>response.html</code> to embed on my website.</p>
  
  <p>But I'm having a problem on my requests getting a <a href="https://www.chromestatus.com/feature/5629709824032768" rel="nofollow noreferrer">CORB</a> error.</p>
  
  <p>This is my snippet code:</p>
  
  <pre><code>fetchJsonp("https://api.instagram.com/oembed/?url=" + url, {
    timeout: 800,
  }).then(function(response) {
    return response.json();
  })
  </code></pre>
  
  <p>My console:</p>
  
  <pre><code>Cross-Origin Read Blocking (CORB) blocked cross-origin response https://api.instagram.com/oembed/?url=&lt;embedUrl&gt; with MIME type application/json. See https://www.chromestatus.com/feature/5629709824032768 for more details.
  </code></pre>
  
  <p>I handle embedding from twitter with the same snipped code accessing <code>https://api.twitter.com/1/statuses/oembed.json?url=&lt;embedUrl&gt;</code> and it works fine.</p>
  
  <p>Since twitter response have a <code>Content-Type: application/javascript</code> it works, but instagram response have a <code>Content-Type: application/json</code> and it doesn't.</p>
  
  <p>How can I make this work?</p>
