Password protected pages show History tab and is clickable and can see that content

Hi there,

Creating a wiki and setting it to password protected works when viewing that page.
It displays
"This post is password protected. To view it please enter your password below:"
However the tab 'History' can be clicked so all the protected content is viewable on the 'general info' area and also able to click 'Compare Revisions'

I think this is a bug so can you look into getting this fixed please.

Kind regards, Ian
