title: Restricting HTML file input to accept only .txt, and not .csv (in Chrome)
body: <p>I tried to filter file format to accept only <code>.txt</code> in HTML. Here's my HTML code:</p>
  
  <pre><code>&lt;Input
   type="file"
   accept="text/plain"
  /&gt;
  </code></pre>
  
  <p>In Safari, it works and only <code>.txt</code> files show up, but in Chrome (63.0.3239.84) the file selector also shows <code>.csv</code> files. </p>
  
  <p>Is it possible to exclude <code>.csv</code> files in Chrome? </p>
