Describe the bug

When using a p-menu in PrimeNG 20, you could navigate to the next menu item with the arrow keys. In PrimeNG 21, this no longer works. The problem is reproducible on the official documentation.

I tracked down the issue to this commit ff18ada when removing the [pBind] again the navigation is working again.
