I have a component which is utilizing react highcharts and I'm attempting to get the typing on everything correct and linted according to the recommended typescript rules. One issue is that chart.events.drilldown's DrillupAllCallbackFunction's "this" is not properly defined. It is defined as Chart but that is incorrect as it is missing drilldown properties as defined here https://github.com/highcharts/highchart ... own.ts#L85 such as addSingleSeriesAsDrilldown and applyDrilldown which has been referenced as a solution such as here: viewtopic.php?t=42340
Version used is 10.0.0 but confirmed missing in 10.2.1 as well. Any help is appreciated.
