This is a little bit of an unexpected one, but it seems that the positioning is impacted by

```css
html body #main-outlet {
  -webkit-backdrop-filter: blur(8px);
  backdrop-filter: blur(8px);
}

```

Removing those lines fixes it for me.

Apparently `backdrop-filter` creates a new block context in CSS, some more info here… [https://stackoverflow.com/a/52937920/1869753](https://stackoverflow.com/a/52937920/1869753)

> This means that your `position:fixed` element will be positioned relatively to the filtered container and no more the viewport. In other words, it’s still fixed but inside its _new_ containing block (the filtered container)
