 See #38114. At the moment, starter content is only applied to the
 customized state if if there is no changeset post existing for the current
 UUID. However, if I have a fresh site and I preview Twenty Seventeen and
 then, without activating, I do a theme switch to another theme that has
 starter content, I should see that theme's starter content merged on top
 of the previous starter content since the site is still fresh. A
 complication here is with the `auto-draft` post/page. The existence of the
 changeset provided a locking mechanism to prevent these posts from being
 created repeatedly in a given session. What needs to be done, however, is
 to ensure that they only get created once for a given theme's imported
 starter content.
