Greetings Ifandbut!

Thank you for your patience in receiving a response for your concern! We've received notice that the Right mouse button is not considered the equivalent of a cancel button. So this is actually considered to be by design.

If this is something you would like to see implemented in the future, you may wish to consider leaving feedback requesting this as an option! This can be done at the following link under Suggestions & Feedback -
