elements-cli unblindrawtransaction cannot unblind own sent payments

まず、getrawtransaction、unblindrawtransaction、decoderawtransactionを使用してelements-cliで問題を再現し、アンブラインド前後のトランザクションIDと各出力を比較します。完了の条件は、unblindrawtransactionが元のtxidを保持し、wallet所有の出力だけでなく、送信された支払いを含む該当するすべての出力をアンブラインドすることです。

There are two bugs:

1. unblindrawtransaction method changes TxId of the transaction
2. it does not unblind all outputs, but only those coming back to the wallet (change or deposits)

Have a look:
