Datatable with virtual scroll broken in 20.1.2

Describe the bug

There was a bug introduced in 20.1.2 where in some cases data table with virtual scroll on is not rendered properly. There are either no rows rendered initially or only one.

Downgrade to 20.1.1 solves the issue.

I suspect this as a problem. https://github.com/primefaces/primeng/commit/eb51995f2ef851a62220c254f55dc77da9d6caca

I do not know when it is happening, what is the root cause, so I am not able to prepare minimum reproducible environment.
