There are two problems with the "View"-Function:

1. the "Show Hidden Pages" option ignored in "Web --> View" mode, always shows all hidden pages in menus.
2. disabled "Show Hidden Pages" option when previewing a hidden page show all hidden pages in menus.

Given the following example tree:
- page 1
- page 2 (hidden)
- page 3 (hidden)
- page 4

The "View"-Function when called from the Backend (Web --> View) always shows hidden pages, completely ignoring the "Show Hidden Pages" option. Pages 1, 2, 3, 4 are shown in menus.

When called from the Page-Tree context menu the "View"-Function shows all hidden pages when previewing a hidden page, completely ignoring the "Show Hidden Pages" option. Pages 1, 2, 3, 4 are shown in menus.

When called from the Page-Tree context menu the "View"-Function shows the hidden pages depending on the "Show Hidden Pages" option when viewing a non-hidden page. Pages 1, 4 are shown in menus.
