SUMMARY

This PR fix the problem that when user undo delete of a native filter, the options under column is gone. The root cause is due to the setState mechanism of the react hook. In the Select component, there is one case that we update the component selectOptions which based on the incoming props:

useEffect(() => {
    fetchedQueries.current.clear();
    setSelectOptions(
      options && Array.isArray(options) ? options : EMPTY_OPTIONS,
    );
    setAllValuesLoaded(false);
}, [options]);

and a logic we use useEffect to update selectOptions:

 useEffect(() => {
    if (selectValue) {
      // ...
      if (options.length > 0) {
        setSelectOptions([...options, ...selectOptions]);
      }
    }
}, [labelInValue, isAsync, selectOptions, selectValue]);

So there is a problem that useEffect knows the state has changed, but the value taken at this time is still the old value.

The solution is we can pass an updater function to transform it so we can use the pending state. see https://beta.reactjs.org/reference/usestate#passing-an-updater-function-to-setstate.
