Blank lines in articleList but articles have proper content

Can't find why but if articleList is visibly overflows from viewport without CSS fix or if new items are added there are sometimes "empty" article lines in the list that either keep being empty or filled with proper content at some random time later.

Found it. It's probably because ItemView.js#L108 prerenders item without invisible class that's removed on real rendering making them visible without content all the way until it's actually added.
