#27503: Heartbeat can cause a post slug to be generated while a title is being
entered

 Priority:  normal        |  Milestone:  3.9

 Severity:  normal        |   Keywords:  needs-patch

 It's possible to be in the middle of entering a post's title at the time
 heartbeat runs. When an autosave fires in this context, the callback
 attached to `after-autosave.update-post-slug` fires, resulting in a slug
 edit box.

 Thus a post title of "Autosaving is a cool thing" ended up with a slug of
 "autos".

 This should really only happen if the post title doesn't have the focus.
 I'm not sure what 3.8 behavior was but I believe autosave would only start
 to run when a field lost the focus.
