title: HTML input file on iOS app, disable "take photo" option
body: <p>I want to disable the "Take Photo" option in an iOS app (WKWebView based) and force users to select photos from library or iCloud. </p>
  
  <p>I can force users to use the camera by the <code>capture</code> boolean attribute:</p>
  
  <pre><code>&lt;input type="file" accept="image/*" multiple capture&gt;
  </code></pre>
  
  <p>But, I can't found anything similar to do exactly the opposite (disable camera). Is that possible with any other HMTL attribute or a different value for <code>capture</code>?</p>
  
  <p>Similar question was asked here: <a href="https://stackoverflow.com/questions/16819845/how-to-disable-take-photo-on-file-input-ios-6">How to disable take photo on file input iOS 6</a>, but the proposed solution: </p>
  
  <blockquote>
    <p>We can also request multiple files using the HTML5 new boolean attribute. In this case, the user can’t use the camera as a source.</p>

  <p>doesn't work for me (I tried with iOS 9+).</p>
