CanSelectCells not working with setGroupSortNormalizer

[Isomorphic]

From a brief test, they don't conflict, and it's difficult to see how there could possibly be a conflict since these functions are not related to each other.

So , please show us a minimal, ready-to-run test case demonstrating how a groupSortNormalizer can break cell selection.

Hi Team,
I am working on SmartGWT version 12.1-p20201118.

I have a listgrid where I have enabled cellSelection by

setCanSelectCells(true);

. In the same grid I also need to implement grouping and hence I am setting the following properties for the same

setGroupByField("mark");
        setShowGroupSummary(true);
        setShowGridSummary(true);
        setShowGroupSummaryInHeader(true);
setNullGroupTitle(Constants.EMPTY_STRING);
setGroupSortDirection(SortDirection.ASCENDING);
        setSortByGroupFirst(true);
        setGroupSortNormalizer(getGroupSortLogic());

I noticed that if I comment the

setGroupSortNormalizer(getGroupSortLogic());

call, cell selection works perfect. But as soon as this call is there, cell selection stops working and whole row is selected.
My implementation of getGroupSortLogic is:

private GroupSortNormalizer getGroupSortLogic() {
        return (final ListGridRecord record, final String fieldName, final ListGrid grid) -> {
            if (record instanceof GroupNode) {
                final GroupNode node = (GroupNode) record;
                if (fieldName.equals(node.getGroupName()) && node.getGroupValue().equals(Constants.EMPTY_STRING)) {
                    return 9999;
                }
            }
            return null;
        };
    }

Would request you to please help me how can I keep the GroupSortNormalizer and also enable cellSelection at the same time.

Thanks.
