Closing nested dialog removes CSS class still needed for parent dialog

[cmicallefcaci]

Describe the bug

Behaviour

When opening a dialog primeng adds the p-overflow-hidden class to the body which hides the scroll bar and adds padding to prevent the content from shifting. When a user closes a dialog then this class is removed from the body.

Bug

When a user opens a nested dialog and then closes it, the p-overflow-hidden class is removed from the body despite the parent modal still being present.

This is demonstrated on your website in the last example

Environment

I am running a web application on an Ubuntu OS, however this issue is present in your examples where you show nested dialogs here

Because of this I do not believe it is an issue with my environment.

Reproducer

No response

Angular version

16.2.12

PrimeNG version

16.0.0

Build / Runtime

Angular CLI App

Language

TypeScript

Node version (for AoT issues node --version)

18.19.0

Browser(s)

Brave v1.66.118, Chrome v125.0.6422.113 (Official Build) (64-bit)

Steps to reproduce the behavior

• Find any nested dialog example (final example on this page)
• Open your browser developer tools so that you have a view of the body template.
• click on the Open Dialog button.
• notice the appropriate css classes being applied to body template
• Open nested dialog
• Close nested dialog
• notice that css class has been removed from body template

Expected behavior

I would expect that the css class which is added when a modal is opened would persist on the body as long as there is a modal open. When the final modal is closed then this css class should be removed.
