[BUG] I can't open more than one book from folder tabs or else the first one gets removed from recents

[PassionateG1t]

Reproduce:

1. open a book from folders tab
2. open a second book folders tab

Expected behavior: Bith books are added to the recents tab.

Actual behavior: the newer book replaces the other one.

This is so catastrophic, I lost all of my highlights because the book was removed from the recent tab.
