AJAX race condition when facet block is inside view header

Problem/Motivation

We have a view were we use the views_block_area module to place the facet block inside the view header.
This causes problems because the /views/ajax and /facets-block-ajax AJAX requests both update the same HTML.
If /views/ajax finishes first, it rewrites the blocks ID and then the replace command returned by /facets-block-ajax does not find the block to replace.
(This in turn makes Drupal.detachBehaviors() call the detach function of behaviors with context = document, which causes all sorts of problems.)

But in this scenario, we don't actually need to call /facets-block-ajax because /views/ajax already updates facets since they are inside the view.

Steps to reproduce

  1. Use views_block_area to place a facet block inside a view header.
  2. Enable AJAX on the view.
  3. Click on a facet link and inspect requests.
  4. Two AJAX requests are sent and their response both manipulate the same HTML.

Proposed resolution

facets-views-ajax.js should not send the request to /facets-block-ajax if the facet blocks are inside the view.
