Comment:

 In reviewing and testing [attachment:"53988.diff"], @SergeyBiryukov I
 think you did resolve an issue. Bailing out without resetting the
 `$output` property to an empty array means `WP_List_Util::get_output()`
 may not be in the right state when invoked. This was why the tests were
 failing.

 The patch looks good to me. Marking it for `commit`.
