Dialog loses draggable functionality when using headless mode with #container slot

[mrmt00]

Describe the bug

The Dialog component can be draggable only when you are not using the #container template.
I found myself trying to build a dialog with an extra slot using all the css classes .p-dialog-* so it looks exactly as the other dialogs and I didnt find a way to make it draggable without having to write a composable with functionality that already lives inside the dialog component
