/**
* Extends WebTestBase::drupalPostAjaxForm() to replace additional content
* on the page after an ajax submission.
*
* WebTestBase::drupalPostAjaxForm() will only process ajax insertions which
* don't have a 'selector' attribute, because it's not easy to convert from a
* jQuery selector to an XPath. However, Ubercart uses many simple, id-based
* selectors, and these can be converted easily
* (eg: '#my-identifier' => '//*[@id="my-identifier"]').
*
* This helper method post-processes the command array returned by
* drupalPostAjaxForm() to perform these insertions.
*
* @see WebTestBase::drupalPostAjaxForm()
