Wrong types inferred when using partial interfaces

[ivancuric]

import { merge } from 'merge-anything';

interface Pokemon {
  name: string;
  type: string;
}

const original: Pokemon = { name: 'Squirtle', type: 'water' };

const updatePokemon = (partial: Partial<Pokemon>) => {
  const evolution = merge(original, partial);
  return evolution; // resolved as `Partial<Pokemon>` when it should be `Pokemon`
};
