Disallow adding a child page under a page it cannot view in default theme

(2) Confluence allows a user to add a child page under a page it cannot view (by choosing Add Page from the context menu while viewing the not accessible error message)

1. I have created a page with viewing restricted just to me.
2. I have tried access the page under a different account. I got the "You cannot view this page" message.
3. From the Add, menu, I have selected Page.
4. I got to the new page editor - I create a new page as a child of the restricted page I am not allowed to view.
5. After I save the page, instead of seeing the page contents, I get the message " You cannot view this page due to inherited restrictions "

For this issue, it's questionable whether it's a bug or a feature.

It can be perfectly explained - the new page was created as a child of a restricted page, and after it was saved, the inherited restrictions kicked in.

But if a user gets into this situation accidentally - the user just chooses "Add Page" to create a new page, without realizing he's currently trying to view an inaccessible page, the user could feel tricked that the content just posted is not accessible.

I personally think it's a bug and users should not be allowed to create child pages under pages they are not allowed to access.....
