@-moz-document crashes csso

[drewwells]

Rules like this cause csso to fail completely

@-moz-document url-prefix() {
    span
    {
        padding:12px 10px 12px 10px;
    }
}

What do you mean by "fail"?

Sorry more to the story, this is the actual code causing the issue. It is invalid CSS.

.live-chat.help .main {
  @-moz-document url-prefix() {
    span {
      padding: 12px 10px 12px 10px;
    }
 }

This is the error thrown on http:https://css.github.io/csso/csso.html

Please check the validity of the CSS block starting from the line #1 csso.web.js:427

@-moz-document url-prefix() {
    .live-chat.help .main span {
        padding: 12px 10px 12px 10px;
    }
 }

=>

@-moz-document url-prefix(){.live-chat.help .main span{padding:12px 10px}}

I don't think it's CSSO's job to rectify invalid input.
