FORCDK-SLIDER-003
Warned by forty-cdk/slider, in development builds only.
[forty-cdk/slider] FORCDK-SLIDER-003: [step]={step} is not greater than 0.Cause
A non-positive step disables grid snapping and makes arrow-key adjustment a no-op (each bump adds 0); a negative step also inverts the [minStepsBetweenThumbs] gap.
Fix
Use a positive [step].
