Since v7.1.0 data labels are misplaced after performing the update of it's rotation

• change highcharts version to the 7.0.3
• reply first step (now the data labels are working correctly)

Recently I've came across this issue on our official forum and wanted to share few possible workarounds:

• Setting data label rotation in initial chart config works as intended
  https://jsfiddle.net/BlackLabel/h31d0wny/
• Set minimal initial rotation value, like 0.0001, before updating with a new rotation value

• Destroy existing data label and create a new one with rotation
