title: Object-fit: cover - is not working with video tags without border-radius
body: <p>I am facing a problem, that I cannot make <code>object-fit: cover;</code> work with video tag because it is overlays outside the parent container, even if I use <code>object-fit: cover;</code></p>
  
  <p>Only one solution works: add a border-radius with some value, like:</p>
  
  <p><code>border-radius: 10px;</code>
  to the video tag css.</p>
  
  <p>Working example:
  <a href="https://codepen.io/anon/pen/qmrvLB" rel="nofollow noreferrer">https://codepen.io/anon/pen/qmrvLB</a>
  Comment in or out <code>border-radius: 10px;</code> line to see what is my problem.</p>
