This is the updated list of prefixes to target your dashboard styles. The main changes here are url('http://www.tumblr.com/dashboard') to url-prefix('http://www.tumblr.com/dashboard'), and a line of code that must be added.

The unexpected side-effect regarding the use of this prefix is while visiting another tumblr blog, the background behind the dashboard/reblog etc. buttons changes to your dashboard theme’s background.

The unexpected side-effect if this prefix is not used is the dashboard theme is not applied to the dashboard if “Enable endless scrolling” is not selected in the Preferences section.

I think I finally found a solution for all of this. This line needs to added to the very end of any dashboard style. It tells the style not to apply the dashboard background to a non-dashboard tumblr site.

I have tested this with Firefox and Chrome. I have also updated all of my applicable styles on userstyles.org.
