TYPO3 Core

Quite a bit complicated to explain but I'll try:

Example Pagetree:

.
├── Page Level 1 A (Usergroups: A and B - ExtendToSubpages: true)
│   ├── Subpage Level 2 A
│   ├── Subpage Level 2 B (Usergroups: A, B and C - ExtendToSubpages: true)
│   │   ├── Subpage Level 3 A
│   │   └── Subpage Level 3 B
│   └── Subpage Level 2 C
└── Page Level 1 B (Usergroups: C - ExtendToSubpages: true)

I would expect that "Subpage Level 2 B" overrides the accessibility of "Page Level 1 A". So "Subpage Level 2 B" should be accessible by usergroups A,B and C. Usergroup C would need a deep link somewhere, as "Page Level 1 A" won't show up in menu.

The current behavior would be a "403 Page Not Found - Reason: Subsection was found and not accessible" if you access "Subpage Level 2 B" with usergroup C.
