Signup and local snapshot

Debian 9.4
Grafana v 5.0.3

We have disabled Signup feature in .INI file.

When I share a dashboard as local snapshot, goto the snapshot I do see data, if I click on Signin(bottom left) I will see the login page, but there is also Signup button, which we don’t see on “normal” login page.

The address is ending with /login?redirect=%2Fdashboard%2Fsnapshot%2abcdyhrofnm3infiTiIn873MJH

Is this that someone else also see?

Strange I tried it again and I can’t reproduce it.
