Object-fit: cover - is not working with video tags without border-radius

Question

I am facing a problem, that I cannot make object-fit: cover; work with video tag because it is overlays outside the parent container, even if I use object-fit: cover;

Only one solution works: add a border-radius with some value, like:

border-radius: 10px; to the video tag css.

Working example: https://codepen.io/anon/pen/qmrvLB Comment in or out border-radius: 10px; line to see what is my problem.

Answer 1

If using border-radius: 1px; (and no one will see that radius) feels too hacky, use a wrapper

body {
  height: 100%;
  display: flex;
  align-items: center;
  justify-content: center;
}

.wrapper {
  width: 50%;
  height: 50px;
  overflow: hidden;
}

video {
  object-fit: cover;
  width: 100%;
  height: 100%;
}

<div class="wrapper">
