Just mentioning I downloaded the 5.8.5.0 download provided by the emailed SourceForge notification. Obviously that link doesn't grab the latest build automatically :-(

Duplicate of https://phabricator.wikimedia.org/T126577
(How can I as task creator mark this as a duplicate?)

I was going to add a bug, but clearly this is just a lack of feature at the moment:

I've mentioned this on enwp (and other places -- "my" script works on explainxkcd for example), but for a workaround reference on phabricator, my [[User:Markhurd/hidetopcontrib]] script can do this, effectively doing what Bawolff suggests at the JavaScript/html level.

This does seem to be fixed: https://en.wikipedia.org/w/index.php?title=User:Markhurd/Sandbox&diff=662749142&oldid=646642979

Sorry, I agree it is working as documented. The Tech News said "to transclude a section with its title" when it meant "to transclude a section by its title".

Has this been added correctly to en.wp?
