Plunkr Case (Bug Reports) Here is stackblitz working sample: https://stackblitz.com/edit/primeng-dialog-demo-xhhkrf?file=src/app/app.component.html

Current behavior

When you open modal dialog with [blockScroll]="true" from another dialog, body scrollbar is enabled.

Expected behavior

Hide body scrollbar if both dialogs has property [blockScroll] set to "true".

Just open dialog and click on "Switch" button.

What is the motivation / use case for changing the behavior?

Does not apply.

Hi, I am facing the same issue but with a combination of dialog opened via DialogService and p-dialog. Steps:

1. Open a dialog via the dialog service.
2. Close it and open a p-dialog immediately.
3. Background starts to scroll as "p-overflow-hidden" class is removed by the dialog service and is not added by the p-dialog again when [modal]="true".

Please let me know if you need more clarification.

The issue persists in 17.11. The scroll under the overlay reappears when opening a dialog from within the sidebar component and then closing it.
