 get_category_parents does not always show full hierarchy when showing
 subcategories. Seems to be related to alphabetical order?

 This example demonstrates the problem. Use the same words & spelling for
 the Category Name - because it matters to the outcome. Parent category:
 "Photography" and give it 2 Child categories: "Event" and "Wedding". Now
 create 2 posts, Post #1: Categories "Photography" & "Event", Post #2:
 Categories "Photography" & "Wedding".

 Now use a theme with a breadcrumbs function that uses get_category_parents
 to generate the breadcrumbs. Yoast SEO plugin will demonstrate the
 problem, for example, as will the Weaver II theme.

 You will get the following output when displaying the single page view of
 each post:

 The Photography->Event post gives this correct breadcrumb:

 ''Home→Photography→Event→Photo-Event''

 The other Photography>Wedding gives this incorrect breadcrumb:

 ''Home→Photography→Photo-wedding''

 note the missing Wedding in the breadcrumb.

 This problem shows on the latest WP 3.5 beta, too.
