ES6 Symbols break handleActions

handleActions doesn’t correctly match actions with types that are Symbols, e.g.

const TEST_ACTION = Symbol('TEST_ACTION')
const OTHER_TEST_ACTION = 'OTHER_TEST_ACTION'
const reducer = handleActions({
  [TEST_ACTION]: () => 'foo',
  [OTHER_TEST_ACTION]: () => 'bar',
}, 'baz')

let state = 'test'
state = reducer(state, {type: TEST_ACTION})
console.log(state) // test (unexpected)
state = reducer(state, {type: OTHER_TEST_ACTION})
console.log(state) // bar (fine)

TEST_ACTION is broken, OTHER_TEST_ACTION is fine.

(Just FYI—while Redux supports symbols as action types, this is generally a bad idea. You won’t be able to serialize your actions and replay them.)
