Add popup - closed without any alert by click save.Alert is not thrown. (without enter data click add and save) -- Yes it will close bcz there is no mandatory field to throw alert..all fields are optional. so,
not an issue
Now, when click on add contact popup, the background page is hidden - This is designed to work like that (contact UI team if u need any clarification)
