How to reproduce

• connect to cms
• open a page
• edit a content

Actual behavior

• if I display the page, the lock is not displayed
• if I close the page and open it again, the lock is not displayed
• if I open the unlock module, nothing is displayed

Expected behavior

• the lock is displayed on the page
• the unlock module displays the lock contents
• Why the lock is on the page and not on the content? I guess it is because we could not know if there is a content locked on the page. So if there is a content and the lock displayed, how I know which content of the page is locked?
