Code: https://codepen.io/OliverJAsh/pen/LEZKPLE

```js
console.log(1, window.navigation.currentEntry.key);

setTimeout(() => {
    history.pushState(null, "", "/foo")

    console.log(2, window.navigation.currentEntry.key);
}, 2000)
```

In non-private windows, it changes as expected after the navigation (`pushState`), but in private windows it does not change.
