Steps to reproduce:
- Be logged-in to an account with the appropriate permissions (suppresionlog)
- Browse to the private Special:Log/suppress of your wiki and select a random log entry there.
- Get a link "permanent link" for such log entry such as https://meta.wikimedia.org/w/index.php?title=Special:Log&logid=39174010
https://meta.wikimedia.org/w/index.php?title=Special:Log&logid=39174010 leads you to the "All public logs" tab of Special:Log but no entry matching that logid is displayed to me even when I have the appropriate permissions to see private log entries.
Log entry matching that logid be displayed, if you have the appropriate permissions of course.
