Description
This PR fixes for #16486
Reason:
The showModal() method of the HTMLDialogElement interface displays the dialog as a modal, over the top of any other dialogs that might be present. That's why toast-notification (popover ) stays non-interactive despite appearing above the modal.
Solution:
When the dialog is opened, move the
umb-backoffice-notification-container
inside the dialog so that the notification can be interacted with, and when the dialog is closed, move the notification back out to the DOM.
