Error when trying to show a tooltip during data updates

### Expected behavior

If data changes are triggered due to the user interaction with the chart, like zoom and pan with [chartjs-plugin-zoom](https://www.chartjs.org/chartjs-plugin-zoom/latest/) plugin, and tooltips are no explicitly configured (default `options.plugins.tooltip` configuration), there should not be unhandled JS errors due to this usage.

### Current behavior

The following error is thrown randomly:

```
[Error] TypeError: undefined is not an object (evaluating 'parsed[iScale.axis]')
getLabelAndValue (chunk-VGFJOCNB.js:969)
createTooltipItem (chunk-VGFJOCNB.js:8917)
_createItems (chunk-VGFJOCNB.js:9260)
update (chunk-VGFJOCNB.js:9293)
handleEvent (chunk-VGFJOCNB.js:9668)
afterEvent (chunk-VGFJOCNB.js:9735)
_notify (chunk-VGFJOCNB.js:5144)
notify (chunk-VGFJOCNB.js:5127)
_eventHandler (chunk-VGFJOCNB.js:6403)
listener (chunk-VGFJOCNB.js:6278)
(anonymous function) (chunk-VGFJOCNB.js:3455)
(anonymous function) (chunk-5HRYR2VN.js:996)
```

It does not happen with so much frequency, but it just sometimes does.

### Reproducible sample

None

### Optional extra steps/info to reproduce

I'm really sorry to not provide a reproducible example, but after many attempts I have not even been able to come up with a sequence of steps to reproduce it.

### Possible solution

In the `getLabelAndValue` functions from the library, check also whether `parsed` is undefined or not before accessing its properties.

### Context

We are trying to reload a line chart data every time that the user does zoom or ends a pan gesture in order to show it to him with a suitable resolution. The client-side data decimation feature of Chart.js did not work well for us in this case.

Also, we use a React setup.
