Resize event feature is not displayed for Scheduler events

[Graham]

We use the Scheduler widget like the following: 

<div id="scheduler" style="height:500px"></div>

$("#scheduler").kendoScheduler({
    editable: {
        confirmation: false
    },
    resources: ko.observable([
        {
            field: "displayMode",
            dataSource: [
                    { text: "Regular-Other-Future", value: 111, color: "#93D095" },
                    ...
            ]
        }
    ]),
    add: function (e) {
        e.preventDefault();
        // Custom adding implementation
    },
    edit: function (e) {
        e.preventDefault();
        // Custom editing implementation
    },
    remove: function (e) {
        e.preventDefault();
        // Custom removing implementation
    },
    moveStart: function (e) {
        e.preventDefault(); // Prevent drag-and-drop
    },
    move: function (e) {
        e.preventDefault(); // Prevent drag-and-drop
    },
    moveEnd: function (e) {
        e.preventDefault(); // Prevent drag-and-drop
    },
    views: [{ type: "day", showWorkHours: true }, { type: "week", showWorkHours: true, selected: true }, "month", "agenda"],
    timezone: "Etc/UTC",
    date: new Date(),
    dataSource: self.dataSource // self.dataSource is KO observable, which is assigned later with kendo.data.SchedulerDataSource()
});

There is no ability for events resizing - when cursor is over an event, cross icon appears but no marks for resizing (as result no resizeStart/resize/resizeEnd events are fired). Please look at the attached screenshot. 

How to make the event resizing feature to be active? It looks like by default it should be available but in our case it is even just not visible. 

Thank you in advance!

Hello Graham,

We tried a similar configuration but it worked as expected. Does this demo work at your side? If yes what is different in your case?
