PrimeNG not able to open multiple dynamic dialogs(nested) with same component

I am trying to open the DynamicDialog with component ProductListDemo. Once the ProductListDemo dialog opens then there is one more button on dialog itself which again open the ProductListDemo component as nested dialog. First time ProductListDemo dialog open fine, but when I try to open the ProductListDemo again from the button present on ProductListDemo dialog. It doesn't open the dialog and dialogService.open return null.

ProductService.ts has dialogService to open the dialog component. Below is the stackblitz for the same.
