Prevent text from updating in AvalonEdit but propagate Event

Question

I know I can subscribe the textEditor.TextArea.TextEntering and set the e.Handled=true to prevent the user from typing a certain character, but the problem with that approach is that it stops the event from bubbling. For instance, I want to prevent the user to type a Carriage Return / Line Feed but allow the event to propagate and eventually validate my window if a validate button is present. Thanks in advance.
