【Bug】"dropdown-cell" cell cannot be pasted correctly

[uioonm]

If the cell type is "dropdown-cell" and allowedValues is set to [{label, value}] type, it cannot be copied and pasted correctly。
My configuration is as follows

{
    kind: GridCellKind.Custom,
    allowOverlay: true,
    copyData: String(value),
    data: {
        kind: "dropdown-cell",
        allowedValues: [
            { label: "110", value: "110" },
            { label: "220", value: "220" }
        ],
        value: String(value)
    }
};

When I copied 220 and pasted it into the cell, there was no response. The value obtained by onCellEdited is still the old value.
Then I tried to check the source code and found that it might be the following problem

When allowedValues is an object array, onPaste cannot return the correct value，and I tried return v as the value, which successfully solved the bug
