Ng-zorro-antd: nz-list-empty is always shown at the bottom of a nz-list

[JoniVR]

Reproduction link

https://stackblitz.com/edit/angular-vrt1mc

Steps to reproduce

1. Create a nz-list with items and nz-list-empty
2. Scroll to the bottom of the list
3. See the nz-list-empty displayed even when items are present.

You can also just look at the v9.1.1 nz-list documentation as the bug is present in those examples as well, I actually forked my stackblitz minimal reproduction from the documentation.

What is expected?

The nz-list-empty only displays when no data is present.

What is actually happening?

The nz-list-empty always displays at the bottom of the list, even when data is present.

| Environment | Info |

| ng-zorro-antd | 9.1.1 |

As I mentioned earlier, you can see it happening in the v9.1.1 documentation.
