Propertie ArrowColor not working

[dcarnelossi]

The ArrowColor property does not change the color.

Tried several ways to define the property without result

    var enjoyhint_script_steps = [
        {
        'next .step1' : 'text1',
        "nextButton" : {text: "Next"},
        'radius': 30,
        'arrowColor': 'rgb(255,0,0)',
        'shape': 'circle'
        },
        {
        'next .step2' : 'text2',
        'nextButton' : {text: "Next"},
        'radius': 30,
        'arrowColor': '#8a2be2',
        'shape': 'circle'
        },
        {
        'next .step3' : 'Text3',
        'arrowColor': 'red',
        'shape': 'circle',
        }
    ];
