title: a href target blank sometimes stucks on about:blank
body: <p>I am trying to open a google docs link in a new tab on browser like:</p>
  <p><code>&lt;a href=&quot;https://docs.google.com/viewer?url={some-url}&quot; target=&quot;_blank&quot;&gt;Google Sheet&lt;/a&gt;</code></p>
  <p>But sometimes link does not open and stucks on about:blank page. But if I press refresh button, the link opens. What can be the problem and how can I fix it?</p>
  <p>I tried on Chrome, Opera and Yandex browsers. All of them acts the same.</p>
