Highcharts范围选择按钮不起作用

Question

我有一个带有范围选择器6h，1d，7d和all的图表。加载图表后，您无法按下所有图表，只能按前三个图表。按1d或7d后，一切都可用。

$('#chart-ranked').highcharts({
    chart: {
        zoomType: 'x',
        events: {
            load: function () {
                this.rangeSelector.clickButton(0);
            }
        },
        height: 500
    },
    title: {
        text: 'Player Skill Rating Progression',
        x: -20
    },
    subtitle: {
        text: 'Updated hourly',
        x: -20
    },
    xAxis: {
        type: 'datetime',
        labels: {
            formatter: function() {
                return moment(this.value).format("YYYY-MM-DD HH:MM");
            }
        }
    },
    yAxis: {
        title: {
            text: 'Skill Rating'
        },
        plotLines: [{
            value: 0,
            width: 1,
            color: '#808080'
        }]
    },
    scrollbar: {
        enabled: true
    },
    rangeSelector: {
        enabled: true,
        buttons: [{
            type: 'minute',
            count: 60 * 6,
            text: '6h'
        },{
            type: 'day',
            count: 1,
            text: '1d'
        }, {
            type: 'day',
            count: 7,
            text: '7d'
        }, {
            type: 'all',
            text: 'All'
        }]
    },
    tooltip: {
        headerFormat: '<span style="font-size:10px">{point.key}</span><table>',
        pointFormatter: function () {
            return '<tr><td style="color:' + this.color + ';padding:0;">' + this.series.name + ': </td><td style="padding:0 0 0 4px;"><strong>' + this.y + ' Skill Rating</strong></td></tr>';
        },
        footerFormat: '</table>',
        shared: true,
        useHTML: true
    },
    legend: {
        layout: 'horizontal',
        align: 'center',
        borderWidth: 0
    },
    series: [{
        name: 'Ranked Solo Duel',
        data: jsonData.ranked_duel
    }, {
        name: 'Ranked Doubles',
        data: jsonData.ranked_doubles
    }, {
        name: 'Ranked Solo Standard',
        data: jsonData.ranked_solo_standard
    }, {
        name: 'Ranked Standard',
        data: jsonData.ranked_standard
    }],
    navigation: {
        buttonOptions: {
            theme: {
                style: {
                    color: '#E0E0E0'
                }
            }
        }
    },
    exporting: {
        buttons: {
            contextButton: {
                text: "Download",
                symbol: null
            }
        },
        filename: 'player_rank_progression_rating_chart',
        sourceWidth: 1200,
        sourceHeight: 1200
    }
});

我在jsfiddle上重现了这个问题。 https://jsfiddle.net/2j4d1y20/

我不确定这是一个错误还是故意的，但我想修复或解决这个问题。
