LESS: @media Queries Nested in Class

[XFFA.IR Bot]

You're supposed to be able to nest @media queries in a class in LESS. Like so:

Less:

.class1 {
  width: 100%;

  @media screen and (min-width: 740px) {
    width: 50%;
  }
}

I haven't been able to get this to work in xF, though. Has anyone else tried this with any luck?
