Info "playlist created" persistent
Steps to reproduce
Create a playlist, the green info message "playlist created" on the popup appears. Close the playlist popup and open it again, the message popup is still there, but it should not.
I guess it's because when you close the popup it's not really closed, just "minimized": if you write something in the playlist title field, but don't validate, it's still there when you re-open the popup.
Not sure if it's a bug or was thought like that, but it's quite disturbing IMHO...
