Regular users cannot move or delete anymore a page created by them which has been converted to terminal

STEPS TO REPRODUCE

1. Create an user (U1)
2. Login as U1 (advanced user)
3. Create a page (e.g. Pag1)
4. Create a WebHome (non-terminal) child to this page (Pag1/Pag2/)
5. On Pag2, click 'More Actions' > 'Move / Rename'
6. Tick 'Rename as Terminal Page'
7. Click 'Rename'
8. Go again to Pag2, click 'More Actions'
9. Observe the options available under 'Manage' section

EXPECTED RESULTS

Since the renamed (now Terminal) 'Pag2' page was initially created by the same user (U1), on 'More Actions' > 'Manage' drop-down section, the 'Move / Rename' and 'Delete' actions are also available.

ACTUAL RESULTS

The user U1 has available only the 'Copy' action.

If the page Pag2 is created from the beginning as Terminal, the 'Move / Rename' and 'Delete' actions are present.

The issue reproduces also on older XWiki versions, including XWiki 11.1, but could not reproduce it on XWiki 11.0.3.
