T173015 is resolved.
Description
Currently, if a user accesses a saved book, there's a banner informing them that ocg doesn't work all that well. When we switch to pediapress rendering, this will no longer be necessary. Books are currently saved in the user namespace and the book namespace
Acceptance criteria
- remove the banner from user-created books page
example user namespace: https://en.wikipedia.org/wiki/User:OVasileva_(WMF)/Books/Trial_Book_1
example book namespace: https://en.wikipedia.org/wiki/Book:13th_Floor_Elevators
