Research direction

Start by reproducing the linked CodePen with sorted and unsorted tickvals, comparing the axis label rotation and overlap behavior. Trace the axis tick-label layout path used by that example, then verify that unsorted tickvals produce the same overlap-avoiding rotation as sorted values.
