When "AutoHide" is set to False, the ShowOn configuration only delays the display of the tooltip.  

Expected functionality is that ShowOn will prevent the display of the tooltip until it has been hovered over for the specified interval.

How can I achieve the expected functionality?

Hello Kevin,

Actually the autoHide:true option is clearing the ToolTip timer (setTimeout) defined by the showAfter option. The event for showing is triggered on mouseenter and the ToolTip is about to be shown (after the delay or immediately) however since the AutoHide option is not active the hiding of the Tooltip is left to be performed by the user (after clicking the button) and there is clearing of the interval performed.

I will update the documentation accordingly.

I am sorry for any inconvenience caused/
