Ajax pagination broken on taxonomy View added to taxonomy archive

Symptoms

There is an issue where AJAX pagination is broken when using a View listing taxonomies and adding it to a taxonomy archive template.

This issue happens when the following conditions are met:

• You have a hierarchical taxonomy, e.g. for cars, which looks something like this:
  • Ford
    –Focus
    –Fiesta
    –Mondeo
    –Kuga
    VW
    –Golf
    –Polo
    –Passat
    etc…
• You create a custom WordPress Archive for this car taxonomy, available at a URL such as site.com/car/ford.
• You add a taxonomy View to this archive which displays all of the sub-terms, i.e. it should display “Focus”, “Fiesta”, “Mondeo”, “Kuga” etc.
• So the View displays car taxonomy terms, and has a Query Filter for parent taxonomy where the parent is set by the archive where the View is displayed.
• You add AJAX pagination, that manually updates via page reload.

The AJAX pagination is broken, the Query Filter for parent taxonomy term becomes ineffective and all terms are included.
