mgwt-List-last styles do not override mgwt-List>li styles without using !important

What steps will reproduce the problem?
1. create app view with celllist
2. define and inject my.css to override .mgwt-List-last style as
{
    border-bottom-style: solid;
    border-bottom-color: #abadb0;
    border-bottom-width: 2px;
}
3. observe the bottom border is missing from the last row cell.
4. append !important all three border-bottom styles.
{
    border-bottom-style: solid !important;
    border-bottom-color: #abadb0 !important;
    border-bottom-width: 2px !important;
}
5. observe the bottom border is now defined for the last row cell.

What is the expected output? What do you see instead?
I expected that the "last" style would override the stock .mgwt-List>li style 
without having to resort to !important 

What version of the product are you using? On what operating system?
mgwt 1.2.0 snapshot, gwt 2.5.1, chrome
