In this comment https://jira.xwiki.org/browse/XWIKI-18617?focusedId=109028&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-109028 Marius Dumitru Florea also notices that the title of the homepage of the application is not updated, and seems to suggest that it used to work in the past, which would mean that this current issue would be a regression... I haven't checked versions older than 12.10.6.
