Multiline data labels - not line splitting, showing array as string twice

Thanks for the great library, been able to make some nice charts but I've got an issue with multiline dataLabels.

Using ng-apexcharts and something similar to the code below to make data labels multiline.

dataLabels: {
        textAnchor: 'start',
        style: {
          fontSize: '20px',
          fontWeight: '600',
        },
        dropShadow: {
          enabled: false,
        },
        formatter: (value, { seriesIndex, w }) => {
          // TODO: split over two lines https://github.com/apexcharts/apexcharts.js/issues/670

          return [`${w.config.labels[seriesIndex]}`, `${value}%`] as unknown as string;

        },
      },

In my case, they are for pie charts

The problem I am having even shows up in some of your documentation examples (different function but I imagine they are conencted):

Any ideas/work arounds would be much appreciated, thanks
