Same issue but a slight variation: With a border set on the label the border also is broken and cuts across the entire chart.

Forked fiddle: https://jsfiddle.net/kennygoff/f5mnjuzt/2/

xAxis: {
  type: 'datetime',
  crosshair: {
    label: {
      enabled: true,
      borderColor: '#000000',
      borderWidth: 1,
    },
  },
}
