Research direction

Start with the linked histogram-chart minimal reproduction and inspect how the crosshair responds to the bottom axis when inverse: true is set. Reproduce the issue with the provided spec, then verify that the crosshair follows the inverted axis normally without breaking the existing histogram behavior.
