hide_pages failed when switch to another visiable page

[RuochengShan]

The hide_pages works well when loading the main page (showing visable pages and hiding the target page). But when switched to a visiable page other than the main page, the page link of a hidden page appears.

hide_pages is purely done by css, so it needs to be done on every page that you want to hide page on
