Bookmarks not working on tables

[pocelka]

I can access the bookmark on mobile phone / desktop, but on tablet I'm not able to click (touch) the bookmark icon on the left.

To Reproduce Steps to reproduce the behavior:

1. Open book on iPad
2. Click on 'hamburger' menu on the left
3. Click on bookmark icon
