On mobile it appears to be possible to reveal links which are hidden by default via user scripts however when clicked these throw errors https://he.m.wikipedia.org/wiki/%D7%9E%D7%99%D7%95%D7%97%D7%93:%D7%A1%D7%A4%D7%A8
It seems from the production logs at least one user is doing something along these lines.
I could replicate by the following:
In JS console run:
$('#collectionListContainer a').attr('style','')
Click "create chapter"
Uncaught ReferenceError: coll_create_chapter is not defined
Developer notes
Either this page should be blanked on mobile, or all the load should be loaded, warts and all.
