Possible bug with column drag and drop when grid and gantt are in the same page

[Vedad]

Hi,

I had to add the grid to part of my gantt page in the app and as soon as I added the grid, gantt drag and drop of columns started to fail.

On column drop lib fails with the following error:

Uncaught TypeError: Cannot read properties of undefined (reading 'lockable')
    at init._allowDragOverContainers (kendo.all.js:311085:87)
    at init._dropTargetAllowed (kendo.all.js:311085:87)
    at init.drop (kendo.all.js:311085:87)
    at init.trigger (kendo.all.js:311085:87)
    at init._trigger (kendo.all.js:311085:87)
    at init._drop (kendo.all.js:311085:87)
    at kendo.all.js:311085:87
    at init._withDropTarget (kendo.all.js:311085:87)
    at init._end (kendo.all.js:311085:87)
    at init.trigger (kendo.all.js:311085:87)

Problem is reproducible in the following Dojo

To reproduce issue, just try to change the order of the columns in the gantt widget.

Result: Widget breaks on drop and any drag or drop is not possible. Browser console shows error described above.

Expected result: Columns reordered

Tested with Chrome and Firefox.

If there is anything else I can do to help, please let me know.
