Description

Update DOMPurify to the latest 2.X version.

Updated package-lock-p3.json to keep using "lockfileVersion": 2.

After converting to P3, I'm now getting errors when running npm run generate-typings:

Looks like it's caused by declare class ChartSeriesElement extends Polymer.Element in vaadin-chart-series.d.ts

[DiegoCardoso]

This error seems to be reproducible in master as well. Any idea what it could be?

[web-padawan]

Nevermind, in V14 we don't publish .d.ts for vaadin-charts e.g. I couldn't find them when installing v6.3.7.

[web-padawan]

LGTM. Probably could mark this as fix: to indicate it's actually a fix in release notes.
