Error on sankey update while hovered

[futpib]

Expected behaviour

No error.

Actual behaviour

A call to chart.update while a sankey edge is hovered results in error.

highcharts.src.js:45176 Uncaught TypeError: Cannot read property 'options' of null
    at object.setState (highcharts.src.js:45176)
    at sankey.src.js:204

Live demo with steps to reproduce

https://jsfiddle.net/L6gq7y54/

1. Hover any edge (hovering nodes does not lead to error)
2. Wait for a random update to hit while hovered (up to 3 seconds)
3. Observe the broken chart and an error in the console

Product version

Highcharts JS v7.1.1 (2019-04-09)

Affected browser(s)

Probably all (but only latest Chrome and Firefox were tested).

Workaround

			if (chart.hoverPoint) {
				chart.hoverPoint.onMouseOut();
			}

			chart.update(...);

Hi @futpib,
Thank you for reporting about the problem. The issue is related with the new option - inactive state.

Internal note
Its regression since v7.0.3.
