It looks that it cuts not last but last but one. E.g. for https://ru.wikipedia.org/wiki/Special:Contributions/Vanek.1000.01 it shows results for Vanek.1000.1 while for https://ru.wikipedia.org/wiki/Special:Contributions/Vanek.1000.10 it cuts nothing.
On try to go to userpage https://ru.wikipedia.org/wiki/Участник:Vanek.1000.00 url gets cut to https://ru.wikipedia.org/wiki/Участник:Vanek.1000.0
while we can see that the account does exist from CentralAuth which works fine: https://ru.wikipedia.org/wiki/Special:CentralAuth/Vanek.1000.00
This seems to affect a number of different URLs with usernames with numbers in them. E.g. https://www.mediawiki.org/wiki/User:01tonythomas redirects to https://www.mediawiki.org/wiki/User:1tonythomas.
Per T117476 it breaks login as well.
