Current behavior

When trying to make a portal or directly call dialog when loading for specific components blocks (lets assume like a dashboard), the body was set with ngneat-dialog-hidden class and blocks entire page scroll.

Expected behavior

Choose which DOM element scroll should be blocked (body, container it attached to etc)

Minimal reproduction of the problem with instructions

constructor(
        private dialogService: DialogService,
        private el: ElementRef
    ) {
      this.dialogService.open(SpinnerBoxComponent, {
            container: this.el,
            closeButton: false,
            enableClose: false,
            width: 'auto',
        })
    }

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

The possibility to control the dialog component per component scope (like dashboard module stats etc) and to not block page scroll.
