Credit card fee record as the event fee

We've discovered and issue which appears to affect any payment processor that returns the card processing fee to Civi.

When paying for an event the card "fee" get recorded as the event fee.

For instance if I pay for a $35 dollar event on the event tab the fee paid for the event is $1.05 (assuming a 3% fee)

A patch for the change in \CRM\Event\Form\participant.php is attached.

We could not find this issue addressed elsewhere.

Thanks
