Thanks for reporting this. I cannot reproduce (if I understand correctly), being logged out in a private window.

I use Firefox 61 (on desktop) and go to https://ru.m.wikipedia.org/wiki/Большая_российская_энциклопедия_(издательство). I click on the [1] of СССР[1]. At the bottom of the screen, I get the Цитата displayed until I click somewhere else:

Does this also happen when you are logged out? Does this also happen when you are logged in and use safemode (see https://www.mediawiki.org/wiki/Help:Locating_broken_scripts )? Any errors in the console of the web browser? Which exact web browsers was this tested with? Please see https://mediawiki.org/wiki/How_to_report_a_bug

Unrelated to the code of the BetaFeatures extension itself, hence removing tag.

@Aklapper: did you tested with enabled Wikipedia βeta features in Settings?

Does this also happen when you are logged out?

Yes, in private tab.

Does this also happen when you are logged in and use safemode

No matters, see above.

Any errors in the console of the web browser?

No, it's empty, just generic messages about deprecated methods.

Other people complain too, see topic in ruwiki - https://ru.wikipedia.org/wiki/Википедия:Форум/Технический#Не_открываются_примечания_в_мобильной_бета-версии, and does not dependent on the browser or device (tested on latest Chrome, Firefox, Opera, Safari).

Ah, I didn't know that there is a general "Википедия Бета-версия" option in the mobile settings under https://ru.m.wikipedia.org/wiki/Служебная:Настройки_мобильной_версии - sorry! (Full steps to reproduce are welcome, as the task description did not mention that.)

Confirming the problem now.

Jdlrobson lowered the priority of this task from Medium to Low.
Jdlrobson moved this task from Incoming to Needs Prioritization on the Readers-Web-Backlog board.

Given the "goal" is low priority (in the we haven't touched it for over a year sense not the priority on phabricator) I'm guessing this should also be low.
@ovasileva we should really make a decision about what to do with the lazy load references feature.

Lazy loaded reference feature will be removed (see T222373)
