When Sending the Client an ingame Message via
NotificationSystem.SendNotificationToPlayerIdentityExtended(sender, 5.0, heading, message, "set:ccgui_enforce image:HudEnter");
and the message is too long to fit in a single line, it will continue in a second line. This leads to a cut off Icon and some text is cut off at the right of the displayed widget. (See Screenshot top) on the bottom of the screenshot you can see how the Widget behaves when disapearing. Interestingly the Cut off Icon gets fixed while disappearing, but not the cut off text on the right.
