What are the steps to reproduce?

I am inserting a notification node (ui_toast). In Properties is select a layout "OK/Cancel Dialog" or "OK/Cancel Dialog with Input". Then I add a Class to the node.

What happens?

The class is not applied on the notification node.

What do you expect to happen?

I except my custom class to be applied to the notification node, so I can target it with CSS

Solution:

The problem is solved by changing line 630 in "main.js":
from
confirm._options.template = '<md-dialog md-theme="{{ dialog.theme || dialog.defaultTheme }}" aria-label="{{ dialog.ariaLabel }}" >' +"

to
confirm._options.template = '<md-dialog md-theme="{{ dialog.theme || dialog.defaultTheme }}" aria-label="{{ dialog.ariaLabel }}" class="' + msg.toastClass + ' >' +"
