4. Change "Type" to "Panel" and below that add "Undefined / Invite Members"
5. Go to "Welcome" page click "Invite Members" -> "Invite members to this site."

8. Click the "minus" button to remove user "test3" from "Members to Invite"

Actual Result: a javascript error is thrown "Uncaught TypeError: Cannot read property 'removeClass' of null" and user "test3" is not removed
