Comment (by spacedmonkey):

 While reviewing this bug, I found a second place, where last_result being
 `null` would be an issue.

 See attached
 [https://core.trac.wordpress.org/attachment/ticket/45299/45299-bug1.diff
 45299-bug1.diff] which is a simple fix. It might have to go in another
 ticket.
