Touch-dragged tooltips do not close on clicks/taps outside the chart

### Expected behavior

Any clicks/taps outside the chart should close the active tooltip.

### Current behavior

The tooltip remains visible even after tapping outside the chart.

### Reproducible sample

https://www.chartjs.org/docs/latest/samples/bar/stacked.html

### Optional extra steps/info to reproduce

This can be reproduced on some of the official samples, e.g., “Stacked Bar Chart”:
1. Start a touch drag on one of the columns.
2. Drag to another column.
3. Stop the touch drag on this column.
4. Tap ouside of the chart.

This issue only occurs on touch devices, but can also be reproduced on desktop using DevTools’ “device mode” to simulate touch events.
