Updating cursor though plotOptions does not update each series

[karolkolodziej]

Expected behaviour

When updating the series cursor through the plotOptions each series should have that property as it is with color.

Actual behaviour

When updating the series cursor through the plotOptions only the first series has updated cursor.
This is not the case when you have column and line but is when having column and scatter.

Is there any indication when this bug is going to be resolved? It's quite an annoying bug in our application as it's unclear to customers when they can click through to zoom in.

Hey @Noppey apologies for not having solved this yet!

I will get someone with more experience to look into it, for the time being there is a (somewhat laborious) workaround you can use, at least going by the fiddle you posted. It involves simply recreating the series which does not accurately receives the updated cursor with the same desired settings as the old, but after updating plotOptions: https://jsfiddle.net/mkb93/3tgk7Lcs/

Internal note:
Logging each series shows that they have series.cursor.options set accurately, but the style-attribute of the series' HTML-objects shows that only one of them receives the cursor-style. The initial setting of the cursor works for both series, it is when it is already set that the bug occurs (which can be seen by removing the initial settings of plotOptions in the OP fiddle)

I understand the workaround, but I don't like the additional complexity in our usecase (not the jsfiddle).
Is it possible to get the bug assigned to someone who has the ability to solve it?

Thank you for your patience @Noppey !

Until the next maintenance is released, there's a more modular drop-in workaround you can use, instead of rewriting your logic. Then after release this can be removed (or not):

// Drop-in workaround for #17878
Highcharts.addEvent(Highcharts.seriesTypes.column, 'afterUpdate', function(options) {
    if (this.options.cursor) {
        this.trackerGroups.forEach(key => {
            if (this[key]) {
                this[key].attr({
                    'style': `cursor: ${this.options.cursor}`
                });
            }
        });
    }
});
