> * Demonstrates the need to move a tooltip.
> * 
> * This example has a table. When you hover over a table item, a tooltip 
> * appears. The tooltip has a link - try to click it.
> * 
> * When the tooltip is in its original position, you cannot move the cursor
> * over the tooltip.
> * 
> * When the tooltip is moved to be under the mouse to allow you to click the 
> * link in the tooltip, you cannot click the tree (e.g. try hovering over the 
> * checkbox, then wait for the tooltip to appear, then try to click the 
> * checkbox).
> * 
> * Change which problem you want to simulate with the MODE constant below.
