Is it possible to have comments stay commented out when using  
sanitize?

For example, I have this in my view:

\<%= sanitize @description %\>

and @description = “”

but sanitize converts:

to  
\<!-- end time --\>

so the words actually shows up on the website.

anyone know if it’s possible to tell sanitize to leave html comments  
alone?

I tried adding this to environment.rb but no luck:  
config.action\_view.sanitized\_allowed\_tags = ‘!–’, ‘–’
