formatCellValue calls after startEditingNew

Hello, I've got a problem in my application which I managed to replicate in the showcase, please try this test case:

isc.ListGrid.create({
    ID: "countryList",
    width: 700, height: 224,
    showFilterEditor: true,
    initialSort: [
        {
            property: "countryName",
            direction: "ascending"
        }
    ],
    dataSource: worldDS,
    fields: [
        {name: "countryName"},
        {name: "continent"},
        {
            name: "government",
            formatCellValue: function (value, record, rowNum, colNum, grid) {
                isc.logEcho(record, "formatCellValue " + rowNum)
            }
        },
        {name: "area"},
        {name: "gdp"},
        {name: "independence", width: 100}
    ]
})

then if you run countryList.startEditingNew() you'll see a WARN:

*15:52:44.505:WARN:gridEdit:countryList:startEditing() passed bad cell coordinates:1000,0, can't edit
    ListGrid.startEditing(_1=>1000, _2=>0, _3=>undef, _4=>undef, _5=>undef) on[ListGrid ID:countryList] @ ISC_Grids.js:2264:97
    ListGrid.startEditingNew(_1=>undef, _2=>undef) on[ListGrid ID:countryList] @ ISC_Grids.js:2456:6
    null.<anonymous>(<no args: exited>) @ [no file]:1:13

and data will be fetched (I wasn't expecting this).

Instead if you run countryList.startEditingNew({continent:"Asia"}) you'll see also many calls to formatCellValue with record === null (for rowNums==0 to 8, and from 992 to 999, for rowNum == 1000, you'll see a record with the continent value).

is this a bug, or has there been some change in behaviour? Currently my code does not expect record to be null, and even the fetch seems unexpected

also note that in my actual use case I've got autoSaveEdits:false

Hello, any news about this issue?

Out of curiosity, I've tried the test case in 14.1 and 15.0 also, and I see the same behaviour.
