Selecting Add from Event modal in topology redirects to add page but the event modal to add trigger for  a broker persistes    

Everytime
    

    1. Enable event option in config map of knative-eventing namespace
    2. Create a broker and associate an event to it
    3. In topology select add trigger for the broker
    4. Since no service is created it will ask to go to Add page to create a service so select Add from the modal 
    

The modal persists
    

The modal should be closed after the user is redirected to the Add page
