If you set HideEvent to "LeaveTargetAndToolTIp", and if you place your mouse over the target (let's say an image), the tooltip displays and after a few seconds it hides. If you set the HideEvent to "LeaveTootip", the tooltip doesn't hide in the same scenario. I am fine with using "LeaveTooltip" to create a persistant tooltip which doesn't hide unless the user moves their mouse off the target, however, it doesn't seem to match up with the avaialble HideEvent options. Shouldn't "LeaveTargetAndTooltip" be the one which persists the tooltip when the user is hovering over the target?
