D3 slider with ordinal values gets stuck on tick 8

I am trying to implement a D3 slider with ordinal values for each tick.

I have used the following slider implementation:
https://github.com/MasterMaps/d3-slider
https://codepen.io/DougManuel/full/avRyMg

Here is my .js (myslider.js) code with the slider implementation:

var data2 = ['18:00','18:15','18:30','18:45','19:00','19:15','19:30','19:45','20:00','20:15','20:30','20:45','21:00','21:15','21:30','21:45','22:00','22:15','22:30','22:45'];

var w = window.innerWidth || document.body.clientWidth,

h = 700;  



drawSlider();  



function drawSlider() {  

    svg = d3.select("body").append("svg:svg")  

        .attr("width", w)

        .attr("height", h);



    svg.append('text')

        .attr('class','timeband')

        .attr("x", w/2)

        .attr("y", h/2)

        .attr('text-anchor','middle')

        .attr('font-family','sans-serif')

        .attr('font-weight','bold')

        .attr('font-size','50px')

        .attr('fill','black')

        .text(data2[0]);



    d3.select('#slider2').call(

        d3.slider()

            .scale(d3.scale.ordinal().domain(data2).rangePoints([0, 1],0.5))

            .axis(d3.svg.axis())

            .snap(true)

            .value(data2[0])

            .on("slideend", function(evt, value) {       

                svg.selectAll("text.timeband")              

                    .text(value)                

            })

    );

}

Here is my html code:

<!DOCTYPE html>

<html>

<head>

    <meta charset="utf-8">

    <meta name="viewport" content="width=device-width, initial-scale=1">

</head>

<body>

    <div id="slider2" style="margin-bottom:30px;"></div>

    <script src="d3/d3.js"></script> <!--D3 Version 3--> 

    <script type="text/javascript" src="d3/slider.js"></script> 

    <!--<script type="text/javascript" src="https://github.com/MasterMaps/d3-slider/blob/master/d3.slider.js"></script>-->

    <link rel="stylesheet" href="css/d3.slider.css" /> 

    <!--<link rel="stylesheet" href="https://github.com/MasterMaps/d3-slider/blob/master/d3.slider.css"/>-->

    <script type="text/javascript" src="js/myslider.js"></script>    

</body>

My slider does not move beyond tick no 8 with the value '19:45'. I think it is dependent on the configuration of the rangePoints function of the scale. I have tried multiple combinations but was not able to figure out the optimal setting.

There is a bug in d3-slider if the stops can be indexed (strings) (line [281]).

if ( value[ 0 ] >= value[ 1 ] ) return;

This line is there to prevent that range sliders value[0] is larger then value[1]. For non-range sliders with string ticks this depends on what string is the current value.

If the string is 20:00 the condition is true and so no animation/positioning of the slider.

Change the line to

if (toType(value) == "array" && value.length == 2 && value[ 0 ] >= value[ 1 ] ) return;

to make the test only valid for range sliders.
