MediaWiki before 1.35.1 blocks legitimate attempts to hide log entries in
some situations. If one sets MediaWiki:Mainpage to Special:MyLanguage/Main
Page, visits a log entry on Special:Log, and toggles the “Change visibility
of selected log entries” checkbox (or a tags checkbox) next to it, there is
a redirection to the main page’s action=historysubmit (instead of the
desired behavior in which a revision-deletion form appears).
