screenshot of bug in action
it's apparently possible for page footer/header widgets to remain visible after changing the zoom level, which looks very ugly.
on a similar note, i'm not sure if it's really a good idea to show these at all on very small zoom levels like 20%, since they're really huge compared to the actual pages then.
