Missing menu animation

[LexanRed]

Reproduction link

https://stackblitz.com/edit/ng-zorro-antd-ivy-1yyma2?file=src/app/app.component.html

Steps to reproduce

Open and close the menu on the left. You will see, the content appears before the div expanded fully.

A transition should be added in order to make it appear more smooth. https://ant.design/components/menu/

In the original version (ant for react) it is working perfectly. Opening and closing for the menu does not make the content jump / suddenly appear.

There is a transition in height, and opacity.

What is expected?

Smooth opening and closing of menu items

What is actually happening?

Content is appearing without transition
