Why can't I add a VF page to the “Feed View” of a feed-based layout in a packaging org?

I have created a feed-based layout in my dev org. This layout has a VF page as a custom component on the Feed View section of the layout. When I attempt to deploy it to the packaging org for our managed package, the deploy fails with "Error: Not a valid custom component".

While investigating, I attempted to manually create a new feed-based layout on this same custom object in the packaging org. I was able to create the layout, but when I attempted to add a VF page to the Feed View, the VF page picker fails to "find" any of my pages. I can add the VF page to the "Details" section (the main part of the layout). It would appear that the Feed View custom component is broken for packaging orgs (those with a namespace). Can anybody confirm/deny and/or point me to the documentation for this?
