Hide Header isn't effective

What is the problem? Describe completely:

Minimalist version   - 0.6.8
Relevant core module - Gmail
Chrome version       - 32.0.1700.107
Operating System     - Xubuntu
Language             - English
Google Apps user?    - No
Other extensions     - None that modify HTML or CSS

I'm not a developer, and have no idea how to code. However, I noticed that the 
"Hide Header" feature in Gmail doesn't seem to be working well enough (there's 
still a HUGE space left at the top where everything else should be). 

There's just one line missing, which could be easily fixed by adding this:

#gba {
    height: 2px !important;
}

Just thought I'd let you know, so it could be included in future versions of 
the module. :)
