Breadcrumb is showing WebHome under some permission conditions

To reproduce:

• Create nested pages P1 and P1/P2/P3. Note: P1/P2 is not created
• Create a new user User1 and new user group Group1. Assign User1 to Group1
• Use Administrator and go to page P1 and limit access to only XWikiAdminGroup
• Use Administrator and go to P1/P2/P3 and grant View permission to Group1
• Use User1 and go to P1/P2/P3. You'll see the breadcrumb displaying the attached screenshot.
