Comment:

 Thanks for the report, @rpayne7264. Previously:

 - [34812] first started populating the cache here. So 4.4 would have
 introduced a bug (not specifically noted here, but related) whereby a
 `WP_Error` object might be incorrectly cached. See #32044.
 - [37573] changed the taxonomy relationship cache structure so that only
 item IDs are stored. This is when the `wp_list_pluck()` call was
 introduced. See #36814.

 So the notice is a 4.6 regression, but there's a related bug going back to
 4.4.
