on_order_update callbacks for orderid not in sequence

Hi,

The callbacks in websockets are not coming in sequence and I'm regularly receiving COMPLETE and OPEN callbacks before UPDATE callbacks. This messed up my algo since I was updating the latest orderid status in redis. My code assumed that orderid was yet to COMPLETE and kept waiting for ever till I manually fixed it. Now I cannot use callbacks and am forced to make a network call and check positions or order history for current status.
Please document such drawbacks of the API so that people can take it into account while designing their systems.

Here's an example where I received callbacks for a orderID in the sequence COMPLETE->OPEN->UPDATE:

{'account_id': 'xx',
  'unfilled_quantity': 0,
  ..
  'order_id': '210607002557637',

 {

  'order_id': '210607002557637',

}
