Bug when moving restricted pages

I moved a child-page with inherited permission from a restricted parent to an unrestricted parent within the tree view in Browse > Pages (listpages-dirview.action)

When looking at the restrictions in edit-mode of the page in the original location, confluence displays a warning that restriction is inherited.
When looking at the restrictions in edit-mode of the page in the new, moved location, no warning or restriction is displayed.

Never the less, I still cannot access the page ("You cannot access this page due to inherited restrictions") even though there is no restriction on the page's new parent!
