I'm stumped at this situation. I have a cookie with the following information:

Name: sessionid
Value: *redacted*
Path: /
Domain: localhost

I try to delete it with the following code in the Console:

document.cookie = "sessionid=;expires=Thu, 01 Jan 1970 00:00:00 GMT;path=/;domain=localhost"

But after I click the refresh button in the Application tab, it seems to have had no effect, and the cookie still has the same value as before.

What am I missing?
