In case it helps, I believe the following steps can reproduce this:

1. Position the cursor over the chart area, such that it causes a tooltip to be shown.
2. Move the cursor out of the chart area, such that the tooltip remains visible.
3. Cause the chart contents to be changed, such that the specific point referenced by the active tooltip element is no longer valid.
4. Move the mouse again. This triggers an inChartArea = false event, so it reuses the previous, now invalid, active elements.
