Align prefix spacing

[hiennguyenvan-agilityio]

I have issue align prefix spacing and some other prefix. After run CSScomb (v3.1.8), I get result

-webkit-box-align: center;
  -webkit-align-items: center;
     -moz-box-align: center;
  -ms-flex-align: center;
          align-items: center;
  -webkit-box-pack: center;
  -webkit-justify-content: center;
     -moz-box-pack: center;
  -ms-flex-pack: center;
          justify-content: center;

A new version will produce result that is a little bit better.

body
{
    -webkit-box-align: center;
       -moz-box-align: center;
    -webkit-align-items: center;
            align-items: center;
    -ms-flex-align: center;
    -webkit-box-pack: center;
       -moz-box-pack: center;
    -ms-flex-pack: center;
    -webkit-justify-content: center;
            justify-content: center;
}
