On iOS 16.4 beta 1 Safari does not fire the "visibilitychange" event when the browser is minimized.

I am having trouble reproducing on iOS 16.4 Beta with:
```
1. Load https://jsfiddle.net/rk7bt8hc/5/
2. Home out of Safari
3. Go back to Safari
4. You should now see
> visibility changed to hidden
> visibility changed to visible
```

Could you please provide more information to help us reproduce?

Is this on iPad or iPhone? Do you have a better reproduction case than the one I wrote above?

This is now fixed in Safari 17
