Forum:Login prompt upon clicking "view source"

I noticed a strange feature when trying to view the source of a protected page when I'm not logged in. Normally, you can just view the source code without being allowed to edit it but now it prompts a "Log in or create an account - To perform this action you first need to log in or create an account - Log in - Create an account" window when clicking on "view source". I already tried this on other Wikia wikis, but Brickipedia seems to be the only one with this behaviour. Help:Page protection doesn't give any info on this.

Does anybody know why this is activated and how you can control this feature (i.e. turn it off)? -- 09:59, December 29, 2009 (UTC) 09:57, December 29, 2009 (UTC)
