It seems that "Save Tag Edits" text appeared on self named buttons not used for translations anymore:
Transifex returns nothing: https://www.transifex.com/stack-exchange/stack-overflow-ru/translate/#ru/english?q=text%3A'Save+Tag+Edits'
Traducir says that translation is made: https://ru.traducir.win/strings/4189
But direct link to transifex returns nothing as well: https://www.transifex.com/stack-exchange/stack-overflow-ru/translate/#ru/english/$?q=key%3A6b259c18b31dc19117983177dd24f847
