JSON import incorrectly parses labels with HTML entities

[nk9]

Expected behaviour

When you import a .json file saved by Highcharts, I expect the chart to be recreated as it was when the chart was saved.

Actual behaviour

If the saved data contains semicolons in the labels (for example if HTML entities are used), the data will be parsed incorrectly and the graph will not be reproduced as it was when it was saved.

Reproduction steps

• Visit the Highcharts editor.
• Press the Open button in the toolbar.
• Import this json as a file:

{"template":{"chart":{"type":"line"}},"options":{"series":[{"data":[["a",4],["b–b",5],["c",6]],"name":"col1, thx","turboThreshold":0},{"data":[["a",4],["b–b",4],["c",3]],"name":"col2","turboThreshold":0},{"data":[["a",3],["b–b",5],["c",7]],"name":"col3","turboThreshold":0}],"data":{"csv":"\"null\";\"col1, thx\";\"col2\";\"col3\"\n\"a\";4;4;3\n\"b–b\";5;4;5\n\"c\";6;3;7"},"yAxis":[{}],"pane":{"background":[]},"responsive":{"rules":[]},"tooltip":{"useHTML":true},"xAxis":[{"title":{"useHTML":true},"labels":{"useHTML":true}}]},"customCode":"/*\n// Sample of extending options:\nHighcharts.merge(true, options, {\n    chart: {\n        backgroundColor: \"#bada55\"\n    },\n    plotOptions: {\n        series: {\n            cursor: \"pointer\",\n            events: {\n                click: function(event) {\n                    alert(this.name + \" clicked\\n\" +\n                          \"Alt: \" + event.altKey + \"\\n\" +\n                          \"Control: \" + event.ctrlKey + \"\\n\" +\n                          \"Shift: \" + event.shiftKey + \"\\n\");\n                }\n            }\n        }\n    }\n});\n*/","theme":false,"settings":{"constructor":"Chart","dataProvider":{"csv":"\"null\";\"col1, thx\";\"col2\";\"col3\"\n\"a\";4;4;3\n\"b–b\";5;4;5\n\"c\";6;3;7","googleSpreadsheet":false,"liveData":false}}}
