In https://en.wikipedia.org/wiki/Special:EditWatchlist there is inconsistent capitalisation in English, "(talk | History)".
"History" comes from "history_short" https://translatewiki.net/wiki/MediaWiki:History_short/en
https://translatewiki.net/wiki/MediaWiki:History_short/qqq - "Text used on the history tab"
So inside the watchlistedit string is a word with a first capital letter
There must be another message "history" with first small letter
