Description:
See https://en.wikipedia.org/wiki/User_talk:Anomie#User_script. If you aren't logged in on a particular browser, then you paste in a Wikimedia URL that is only accessible to Admins/whatever and that includes doing an action (e.g. deleting) on multiple items (log entries, old versions of pages, etc.), and then you log in and click "return to X", you get an error message. An example of such a URL is https://en.wikipedia.org/w/index.php?title=Wikipedia%3ASandbox&action=historysubmit&revisiondelete=1&diff=477738682&ids%5B477738682%5D=1&oldid=477736475&ids%5B477736475%5D=1&ids%5B477734577%5D=1. The error message you get when trying to return to the page is:
"Invalid target revision: You have either not specified a target revision(s) to perform this function, the specified revision does not exist, or you are attempting to hide the current revision.
Return to Main Page."
If you are already logged in, pasting in the URL works fine.
