position is not increased in AsynchronousFileChannel.sink

[somdoron]

In AsynchronousFileChannel.sink, the position is not increased when sending ByteBuffer to the underlying channel:

 ZStream
   .repeatZIOWithSchedule(
     write(buffer, currentPos),
     Schedule.recurWhileZIO(Function.const(buffer.hasRemaining))
   )
   .runSum

Between each call to write here the position must be advanced. writeChunk seems to do it correctly:
