Flexbox container in Chrome doesn't get 100% height

Flexbox column container inside another flex container doesn't get 100% height in Chrome, but in Firefox and Edge all ok.

Codepen example

.container {
  display: flex;
  flex-direction: column;

  height: 100%;
  width: 100%;

  .inside-container {
    display: flex;
    flex-direction: column;

    height: 100%;

  }
}
