LibWeb: Ignore document's box during overflow clip rect calculation

Reduction of bug:
```html
<!DOCTYPE html><style>
html {
    overflow-x: hidden;
    overflow-y: scroll;
}
div {
    background: orange;
    height: 1000px;
    width: 500px;
}
</style><body><div>
```

Fixes https://github.com/SerenityOS/serenity/issues/21690 and painting
on many other websites (null.com, servo.org).
