Summary
Without this, if init is called multiple times (like in Vue InstantSearch), multiple event listeners are attached, as well as the helper being recreated. This causes the references from the first init call to no longer being correct later in the instance.
Since we save the references in the very first call of getWidgetRenderState in most widgets (
if (!refine) refine =
), the helper reference needs to stay stable.Result
This fixes algolia/vue-instantsearch#911 by avoiding to have a different helper instance when init gets called multiple times.
