The time data is not sorted, and I tried to sort the markers after addControl, it is not working as well.

Hi, I try to use the leadletslider for the markers based on time. The marker_list is a list of the markers like L.marker(latlng, { time: feature.properties.time, icon: treeIcon });

I tried to sorted the marker_list based on the time, but once passed into the layerGroup, the seq is not persistent.

var layerGroup = L.layerGroup(marker_list);
var sliderControl = L.control.sliderControl({
        position: 'sliderright',
        timeAttribute: "time",
        layer: layerGroup,
        range: true,
        timeStrLength: 22,
        showAllOnStart:true
   });

mymap.addControl(sliderControl);
sliderControl.options.markers.sort(function(a, b) {
        return (a.feature.properties.time > b.feature.properties.time);
});
sliderControl.startSlider();

I also try the method others recommended to sort the markers after addControl, and the slider is still not in time order, how can I fix it? Thanks
