Description

When a Notification is created directly after opening an ConfirmDialog then the message in the ConfirmDialog is not visible. More precisely, it is not even added correctly to the dialog.

Interestingly, if the order is reversed and the Notification is created first, this bug does not appear.

Possibly this is related to how the message properties are handled in the LitTemplates.

Expected outcome

Both components should display their message texts without interference.

Minimal reproducible example

		ConfirmDialog appConfirmDialog = new ConfirmDialog();
		appConfirmDialog.setText("message");
		appConfirmDialog.open();

		Notification notification = new Notification();
		notification.add("Example notification");
		notification.setOpened(true);

Steps to reproduce

1. Add snippet above to a view
2. Notice that message is not visible in the dialog
