Gauge chart throws error if no yAxis.labels config is provided on styled mode

[DiegoCardoso]

Expected behaviour

Charts should work if no configuration for yAxis.labels is provided in styled mode. It works if not in styled mode.

Actual behaviour

Chart is not fully display and and error is raised on console:

VM570 highcharts-more.js:22 Uncaught TypeError: Cannot read property 'fontSize' of undefined

Live demo with steps to reproduce

Run the code at:

You can uncomment the rotation code to see it working as expected.

Product version

Tried first for Highcharts 5.0.14 but could also see the same behaviour for 6.0.7.

Affected browser(s)

Tested on Chrome
