I'm facing an issue with the Highcharts navigator. When I create the navigator using the navigator attribute within the Highcharts configuration, a double-finger scroll over the chart zooms in/out both the chart and the navigator simultaneously. However, when I implement the navigator using the Highcharts.navigator object, the double-finger scroll only zooms in/out the chart, but not the navigator.

const navigator = Highcharts.navigator('navigator-container', {

Any help with resolving this issue would be greatly appreciated.
This issue looks like a bug in the standalone navigator module. Reported here: https://github.com/highcharts/highcharts/issues/21642
As a workaround, you can add support for mousewheel event. For example:
const axis = chart1.xAxis[0];
Highcharts.addEvent(axis, 'setExtremes', (e) => {
if (e.trigger === 'mousewheel') {
navigator.setRange(e.min, e.max, true, true, {
trigger: axis
});
}
});
