defaultChartOptions loads chart, but editor UI controls aren't set the values in the options

[Nexlen]

Expected behaviour

Options for controls are inherited from the defaultChartOptions object.

Actual behaviour

The minute the user clicks any option the template defaults are set. Making it impossible for a user to adjust a single value without resetting all the other values.

Reproduction steps

create an editor with defaultChartOptions.

var data0 = '"name","val"
"Users",4054
"Premium", 725';

highed.Editor(document.body,{defaultChartOptions: 
                    {"title": { "text": "Accounts"},"subtitle": { "text": ""},"exporting": {},"chart": { "type": "pie", "polar": false},"plotOptions": { "pie": {"allowPointSelect": true,"cursor": true,"showInLegend": true,"innerSize": "60%","dataLabels": { "enabled": false} }, "series": {"animation": false,"dataLabels": {} }},"series": [ {"name": "val","turboThreshold": 0,"_colorIndex": 0,"_symbolIndex": 0,"marker": {},"type": "pie" }],"data": { "csv": data0, "googleSpreadsheetKey": false, "googleSpreadsheetWorksheet": false},"yAxis": [ {"title": { "text": ""},"labels": {} }],"colors": [ "#3d5afe", "#f44336", "#76ff03", "#ffeb3b", "#512da8", "#37474f", "#5d4037", "#4caf50", "#9575cd", "#f06292"],"xAxis": [ {"title": {},"labels": {} }],"lang": { "thousandsSep": ","},"credits": { "enabled": false}}
                    });

The Editor loads visually:

However the options are out of sync for the controls

The minute the user clicks any option the template defaults are set. Making it impossible for a user to adjust a single value without resetting all the other values.
