Replication steps:
Assuming you have javascript turned on

1. Create a course
2. Add the feedback activity to the course
3. Edit questions
4. Select a question type from the drop down menu

Expected: Item gets selected, click on "Add question to activity" to add activity

Actual: Item gets selected and automatically added to the activity

This makes the button redundant for browsers with javascript turned on and is a source for potential confusion. I understand why we need the button there when javascript is not enabled in the browser, is there any other consideration I'm missing here?
