Visibility API is not working after window.open in Chrome

Question

I was trying to use Visibility API, but it is not working for a child. The minimal example to reproduce:

<script>

document.onvisibilitychange = () => {
      console.log(document.visibilityState);
    }

if (!window.opener) {
    window.open(window.location.href, '_blank');
}

</script>

After that, the parent window still prints "visible"-"hidden", but child prints "hidden" once only on refresh.

It works fine in the latest Opera browser, but not in the Chrome

To be honest, when I came to this minimal reproduce, I'm stuck and have no idea where to dig. Any ideas what could be wrong?

There are currently two open issues (1107556, 1019406) for the Visibility API that might be related. – Ponceau

@Ponceau Unfortunately, both are not related. Thank you. – Basuto

I also stumbled over this issue. I think that this bug was introduced in Chrome 84. I testet it with version 83 and it worked as expected. The current Canary-Build (Version 86) is also working.
