title: PDF file not downloading with HTML5 download attribute
body: <p>I have a download attribute on two different anchor tags. One is for an Excel file and one for PDF. The Excel file downloads. The PDF opens in new tab instead. Why is this happening? Code below:</p>
  
  <pre><code>        &lt;div class="col-2 center"&gt;
              &lt;a download href="files/excel-sample.xlsx"&gt;
                  &lt;img src="img/excel-logo.png" /&gt;
              &lt;/a&gt;
          &lt;/div&gt;
          &lt;div class="col-2 center"&gt;
              &lt;a download href="files/pdf-sample.pdf"&gt;
                  &lt;img src="img/pdf-logo.png" /&gt;
              &lt;/a&gt;
          &lt;/div&gt;
  </code></pre>
