Steps to Recreate:
1) Log in as administrator to drupal site
2) Navigate to http://example.com/admin/content/filter
3) Filter on a "Category"

What I Expected
Results should be paginated as they are with any other filter, typically 50 / page with a pager at the bottom

What I Experience
There are five pages according to the pager at the bottom. Page 1 has 6 results. Page 2 has 4 results and page 3 has 9 results. The results on each page are shortened from the correct amount of 50
