@Extent don't work on a @import

[Google Code Exporter]

What steps will reproduce the problem?
1. i create a file stylein.scss
2. then create the second file style.scss
3. then import the stylein.scss to the style.css and try to use a @extend on a 
class of style.css and the extend don't show erors, just do nothing.

/*star of file stylein.scss*/
.error{
  border: 1px #f00;
  background-color: #fdd;
}
/*end of file stylein.css*/

/* start od file style.scss*/
@import "stylein.scss";

.seriousError {
  @extend .error;
  border-width: 3px;
}
/* end od file style.scss*/

What is the expected output? What do you see instead?

/* star expected output */
.error, .seriousError {
  border: 1px red;
  background-color: #ffdddd;
}
.seriousError {
  border-width: 3px;
}
/* end expected output */

/* start received output */
.error {
  border: 1px red;
  background-color: #ffdddd;
}

.seriousError {
  border-width: 3px;
}
/* end received output */
