$context not on type Element when accessing activeElements from click event

### Expected behavior

I expect to not have to type cast and do dynamic check to access a property that is there.

### Current behavior

```
onClick: (event, activeChartElements, chart) => {

if (isEmpty(activeChartElements)) {
return;
}
const { element } = activeChartElements[0];

if ('$context' in element && typeof element.$context === 'object') {
const context = element.$context as { raw: { x: string; y: number } };
if ('raw' in context) {
const rawDataPoint = context.raw;
}
}
```
