When the rotation is set to 90 or -90 and the grouped-categories module is used, the x-axis labels become shifted. This behavior occurs inconsistently, depending on the environment.
I was able to reproduce the issue on Android/Chrome.
More details:
highcharts/highcharts#23364
(Note: In my environment, the useHTML option does not affect this behavior.)
Demos:
Without the module (labels render correctly):

With grouped-categories (label shift reproducible on Android/Chrome):
