Based on https://github.com/algolia/react-instantsearch/tree/master/examples/react-router.

Shows 2 issue when using a product type selector that removes DOM elements:

1. onSearchStateChange() is called once for every item removed from DOM--causes duplicate history issues requiring hack fix,
2. 2x HTTP requests to Algolia (b/c invokes both onExternalState() & onWidgetsUpdate()). The first request is useless because it does not have correct refinements for the new DOM items. Ideally, would like to disable that request somehow (possibly via passing false to refine() within a custom menu component used in ProductType.jsx).

Start the example

yarn install
yarn start
