Ticket editor app is closing whenever I am clicking anywhere outside the ticket editor app

Greetings!

I have a support Ticket editor app. It closes the app whenever user clicks outside the app. I want to override this default feature. I just want to not close the app whenever user click outside the app.

Please see attached video that will help to explain my issue
