Members of the confluence-administrators group are able to edit pages they do not have permission to

Summary

Members of the Confluence Administrators group are able to edit pages they don't have permission to. In addition, when attempting to edit a page without permissions, clicking Close results in a blank page.

Steps to Reproduce

1. Make User A as the member of confluence-administrators group
2. User A creates a space and makes User B the only Space Administrator
3. User A goes to the page and the edit function is enabled
4. User A Clicks Edit and starts to make changes
5. User A finishes making changes to the page and clicks Save (which is enabled)

Expected Results

User A should not be able to edit the page.

Actual Results

1. User A's changes are saved
2. User A gets blank page below main Confluence top navigation bar when clicking Close after entering editor

Workaround

There are a few workarounds to this:

1. Most importantly, Atlassian recommends not using your administration account for regular use of Confluence. Create separate admin and user accounts instead.
2. Until CONF-4616 is fixed, grant administrators "System Administration" permission but do not put them in the "confluence-administrators" group if you do not wish them to have access to all content in your system. (This is in relation to the original bug.)
