Custom `getFacetedUniqueValues` does not update on rerenders

Describe the bug and the steps to reproduce it

I am trying to implement custom server-side column faceting, as suggested in the docs.

So I am getting unique values from the server and expect to plug them into the table by updating getFacetedUniqueValues function, like this:

  const [manualFilterValues, setManualFilterValues] = useState(
    new Map<string, number>([["placeholder", 1]])
  );

  // Emulating getting filter values from server
  useEffect(
    () =>
      setManualFilterValues(
        new Map<string, number>([
          ['value1', 1],
          ['value2', 1],
        ])
      ),
    []
  );

  const table = useReactTable({
    ...
    // Plugging current server filter values into getFacetedUniqueValues
    getFacetedUniqueValues: (_table, _columnId) => () => {
      return manualFilterValues;
    },
  });

However, getFacetedUniqueValues seems to be memorized and calling column.getFacetedUniqueValues() only ever returns data from the first render ('placeholder' in this example).

Example from the docs also causes error upon render, as instead of this:

    getFacetedUniqueValues: (table, columnId) => {
      ...
    },

getFacetedUniqueValues expects a factory:

    getFacetedUniqueValues: (table, columnId) => () => {
      ...
    },
