We've got a RadCartesianChart with a BarSeries. We added the ChartTooltipBehaviour with a custom ContentTemplate. It's difficult to hover the mouse over bars with very small or zero values to get the tooltip to show, so I enabled `SnapToClosestPoint` for the tooltip. This works great for getting the tooltip to appear when hovering in the area above a bar, but if the tooltip gets rendered at a location where the mouse pointer is inside the tooltip, then the tooltip appears, disappears, appears, disappears, etc.

Has anyone else run into this issue? Anyone solved it?

Nevermind. I just needed to set `IsHitTestVisible="False"` on the root element in the content template. Easy peasy.
