Comment (by boonebgorges):

 philbirnie - Aha, thanks for the update. This is the same problem (and
 solution) as what I described here:
 https://core.trac.wordpress.org/ticket/27193#comment:10 In short, when you
 set up a new `WP_Query` object, the `get_posts()` method is automatically
 called internally during the setup process. Invoking that method again can
 cause the kinds of query_var stomping that you've described here. We ought
 to have better documentation of this behavior.
