ConfirmationDialog renders to an unconnected div #4011
Description
Description
ConfirmationDialog currently uses Dialog, which uses a Portal. However, ConfirmationDialog implicitly relies on the Portal as a side effect, because it renders into a div which never gets connected into the DOM.
Steps to reproduce
Remove <Portal> from the <Dialog> element, and see failures in <ConfirmationDialog>.
