In `commonMain`: ```@JsExport public interface ZSerializable { public fun serialize(outputStream: ...

# multiplatform

[Edoardo Luppi]

In `commonMain`:

@JsExport
public interface ZSerializable {
  public fun serialize(outputStream: ZOutputStream)
}

public expect interface ZOutputStream {
  ...
}

in `jsMain`:

@JsExport
public actual interface ZOutputStream {
  /**
   * Returns a copy of the internal byte buffer.
   */
  public fun getBuffer(): Buffer

  ...
}

Kotlin complains about ZOutputStream not being exportable, and when generating the TS declaration it doesn't import the Node Buffer type.
Is this working as expected or is it a bug?
