I've a question regarding the interface: Is RBF currently supported? (I haven't found it in the FAQ).

Recently I started an exchange and saw the fee of my transaction was too low, so I RBFed it, and the TXID of the transaction changed. However, in the exch interface, the original transaction ID was still shown as the deposit transaction, even after several refreshes. To be sure, I double spent the transaction before it got confirmed and started a new exchange.

My question is that if the RBFed transaction gets finally confirmed, will it be recognized by the exchange?
