Describe the bug and the steps to reproduce it

Description bug

When a parent has only one node and this node is selected, function getIsSomeSelected() return all as false

Additional

See that in my object, subRow has only one item, the problem only occurs in this case. If you add one more item totaling 2 children, it works correctly

My impression is that getIsSomeSelected returns false for any number of subrows if they are all selected. (getIsAllSubRowsSelected() returns true in this case).

You should be able to do row.getIsSomeSelected() || row.getIsAllSubRowsSelected() to get what you want, I think?

I've asked in discord whether adding a row.getIsAnySubRowsSelected() would be accepted.
