Thanks to Russian Wikipedia user AllaRo, we’ve noticed a bug in localisation: AJAX call that seems to check thanks log for edits that were thanked by me or other people doesn’t receive gender settings of either me or the person that I am thanking. So when I thanked a person with she/her preference, it gets displayed afterwards like this:

https://ru.wikipedia.org/wiki/Википедия:Форум/Технический?action=history

(текущ. | пред.) 19:20, 23 марта 2018‎ AllaRo (обсуждение | вклад)‎ . . (161 350 байт) (+1096)‎ . . (→‎Благодарность в закладке «История»: новая тема) (отменить | отблагодарён)

https://ru.wikipedia.org/wiki/Википедия:Форум/Технический?action=history&uselang=qqx

(parentheses: (cur)(pipe-separator)(last)) 19:20, 23 (march) 2018‎ AllaRo(word-separator)(parentheses: (talkpagelinktext)(pipe-separator)(contribslink))‎ . . (parentheses: (nbytes: 161,350)) (parentheses: +1,096)‎ . . (parentheses: →‎Благодарность в закладке «История»: новая тема) (parentheses: (editundo)(pipe-separator)(thanks-thanked))

As you can see, it passes no parameters in the message thanks-thanked that is replacing a thanking link (when both Saint Johann in my case and AllaRo should be passed), so in languages with gender-specific words this tool is misgendering people (instead of отблагодарён above [he was thanked], it should be отблагодарена [she was thanked]). The message on Translatewiki is fine, the problem seems to be with the script: https://translatewiki.net/wiki/MediaWiki:Thanks-thanked/ru

This should be easy to fix, so I hope someone can do this ASAP. Related to T96527.
