title: <input accept="image/tif does not show *.tif files
body: <p>I have the following HTML tag:</p>
  
  <pre><code>&lt;input id="inputButton" name="buttonAdd" type="file" class="upload" accept="image/bmp, image/jpg, image/jpeg, image/png, image/tif, image/tiff, application/pdf" multiple/&gt;
  </code></pre>
  
  <p>When I click on the button to select a file to upload, the available file types are initially filtered, as expected. The filter does show files with a *.TIFF extension, but it does not show files having only *.TIF extension (see the attached screenshot)</p>

  <p>I am using Internet Explorer 11 on Windows 7 and I MUST ALSO enable the functionality for *.TIF files. </p>
  
  <p>Could somebody help me?</p>
