Emmet autocomplete issue

[name-k]

I don't know if it is a language-stylus or an emmet issue, but here it is:

This will autocomplete (ie on tab press):

.class1
  display block
  m10 // <-

.class2
  display block

This will not:

.class1
  display block
  m10 // <-

.class2 {
  display block
}

{} isn't recognized in stylus.
