plotOptions for specified series are not applied when using setOptions

[goransle]

Expected behaviour

The series should be rendered the same way as when the option is provided in the chart function.

Actual behaviour

The chart is rendered using values from plotOptions.series and not plotOptions.mapline

The same issue is visible for e.g. pie series: https://jsfiddle.net/BlackLabel/trxje5fm/

Internal note:
In short: Highcharts.setOptions({ plotOptions: { series: ... }}) is not implemented/supported.

Looks like Series's setOptions should have typeOptions, plotOptions.series order flipped in

highcharts/ts/Core/Series/Series.ts

Lines 826 to 827 in a31cf60

	typeOptions,
	plotOptions.series,

but there is no difference between defaultOptions.plotOptions.series and userOptions.plotOptions.series (only plotOptions.series is used in the merge) so those 2 should be created instead of the existing one and merged in order defaultOptions.plotOptions.series, defaultOptions.plotOptions[series.type], userOptions.plotOptions.series (and the rest as is).

P.S. watch out for Stock and exporting
