Description

With a custom tooltip, as shown with the following code, the tooltip will "flicker". This is due to the mouse over handler being repeatedly invoked as shown by the stack at the bottom of the report. The ToolTipManager should position the tooltip such that the tooltip doesn't display over the component which issues the tooltip.
