Visibility show-if macro not working for anonymous user

[Z He]

Hi, all,

My purpose is to show some content to anonymous user (make it public) using excerpt-include macro and "show if" from visibility macro. 

The anonymous users do not have view access to the original page. If I add "anonymous" user for show-if, the rendering will show ERROR below:

"User 'null' does not have permission to view the page".

May I know is this correct or I miss anything? 

Thanks in advance!
