After confirming the action from Special:PagePreparation, I got a link to https://www.mediawiki.org/wiki/Extension:ConfirmAccount?action=edit and in the history I see https://www.mediawiki.org/w/index.php?title=Extension%3AConfirmAccount&diff=1107033&oldid=1012488
- The link should not append ?action=edit but use fullurl: https://www.mediawiki.org/wiki/Help:Magic_words#URL_data
- the edit summary should be in content language, not in my interface language.
