Code editor doesn't show method deprecation warnings for the Confluence API

The above script is using SpaceManager's getPersonalSpaceKey method. According to the docs https://docs.atlassian.com/atlassian-confluence/6.6.0/index.html?com/atlassian/confluence/spaces/SpaceManager.html, this method has been deprecated since 5.2. As in Jira, the deprecated method should be underlined in yellow and the user should be told what they should be using instead.
