reselect: TypeScript types appear to be broken in 4.1.5

When upgrading from 4.1.4 to 4.1.5, we started seeing a bunch of TypeScript complaints:

spec/javascript/responses/selectors_spec.ts:120:29 - error TS2322: Type '{ responses: { is_selected: boolean; }[]; are_all_selected_across_pages: boolean; meta: { pagination: { total_count: number; }; }; campaign_data: { doc_pages_count: number; }; }' is not assignable to type 'never'.

120     expect(canGeneratePdf({ responses })).toBe(true);
                                ~~~~~~~~~

const canGeneratePdf = createSelector([getSelectedResponsesCount], (selected_responses_count) => {
  const can_bulk_download_pdf = Feature.isActive('responses/bulk_download_pdf');

  return can_bulk_download_pdf || selected_responses_count <= default_page_size;
});

Not sure why the type never is being inferred from the arguments.
