13.1d SetFilterItem with canExpand:true and expandedPickListFields

[Blama]

Hi Isomorphic,

please see this testcase (SNAPSHOT_v13.1d_2024-06-13). I think there are some strange things happening here:

1. No fields are displayed on click on expand. I'm not sure I can or should modify MultiPickerItem.pickList here, but I think there should be fields displayed by default.
2. There is a fetch for rows startRow:125, endRow:221 on expand
3. nextShipment is not in the data

isc.ListGrid.create({
    ID: "supplyList",
    width: 500,
    height: 300,
    alternateRecordStyles: true,
    dataSource: supplyItem,
    fields: [{
            name: "SKU"
        },
        {
            name: "itemName"
        },
        {
            name: "description"
        },
        {
            name: "category",
            filterEditorType: "SetFilterItem",
            filterEditorProperties: {
                expandedPickListFields: ["category", "unitCost", "nextShipment"],
                canExpand: true,
                optionFilterContext: {
                    summaryFunctions: {
                        "unitCost": "avg",
                        "nextShipment": "min"
                    }
                }
            }
        }
    ],
    autoFetchData: true,
    showFilterEditor: true,
    filterOnKeypress: true,
    fetchDelay: 500
});

Best regards
