You could try to reproduce with the System Load Viewer in playground. 
Another way I can reproduce is something like this:
- hover over system load viewer applet -> tooltip and plasmoid-handle appear
- move the mouse over the plasmoid-handle above the tooltip, be quick,
  somehow the tooltip should not disappear
- now leaving the tooltip without hitting the plasmoid will get you "free",
  i.e. now the tooltip stays there forever :)

It's certainly very rare cases where this can happen, but it does happen.
