[REACT] [GANTT] Fill down scheduler direction does not work always

[ext_mkucanda]

Hi,

Our customer has reported a case where fill down scheduler direction is not working, and I manage to reproduce it in your example: https://bryntum.com/products/gantt/examples/resourceutilization/

I adjusted your example a little bit to show constrainttype and schedulingdirection columns:

const gantt = new Gantt({
    project,
    dependencyIdField : 'sequenceNumber',
    resourceImagePath : '../_shared/images/transparent-users/',
    appendTo          : 'container',
    collapsible       : true,
    header            : false,
    minHeight         : 0,
    viewPreset        : 'weekAndDay',
    tickSize          : 40,
    columnLines       : true,
    startDate         : '2024-01-16',
    selectionMode: { cell: true }, // Enable cell selection
    features: { fillHandle: true }, // Enable fill handle
    columns           : [
        { type : 'name', width : 280 },
        { type : 'resourceassignment', showAvatars : true, width : 170 },
        { type: 'constrainttype' }, // I added this column
        { type: 'schedulingdirection' } // I added this column
    ]
});

Steps to reproduce the issue:

1. Make sure that you have a couple of tasks in your Gantt
2. Make one task Scheduling Direction: Backward
3. Bellow make one task Scheduling Direction: Forward (see attached video)
4. Try to fill down Backward cell value over Forward (This should change value of the Forward value to Backward)
5. Error: Value of the cell is not changed

Is this for whatever reason expected behaviour in this case, or this is a bug on your side?

I used the code you shared, but I can't reproduce it

Am I missing something?
