Component overlay is not disabled in CM for a channel with a restarted review, but only when you open if from the Project's Channels tab

• Create a project and add a channel
  (Optionally: add an xpage to the project as well)
• Start review for the project
• From the Project's Channels tab, reject the channel
• Open the project channel in the CM: the component overlay button is enabled and hst pages are editable (this is correct)
• Back on the Project's Channels tab, restart the review for the channel.
• Click on the Experience manager icon in the navapp to go back to the project channel: the component overlay button is disabled, no containers are displayed, the channel (hst pages) isn't editable. This is correct.

• Go back to the Project's Channels tab and now open the project channel by clicking on the channel on the Channels tab: the component overlay button is enabled, containers are displayed. This is incorrect.

As the containers are all locked, the channel isn't editable: it is just that the overlay is displayed while it shouldn't be. 

Actually, the channel doesn't have to be rejected first: if you start the project review and then open the channel from the channels tab, this behaviour already occurs...
And also for an approved project.
