Bug description is pretty much all there in the title. The tooltips at various points in the tutorials are rendered off-screen. You can edit the DOM to move them back on-screen, but it is awkward. As a second note, I think the text of the tooltips for the Jukebox tutorial is out of sync with the current state of the GUI. They refer to buttons which I don't believe are onscreen. Just flagging this, but it could also just be me not spotting what the tooltips are indicating.
