Your post moved me into doing a little experiment on my own.

I bought a bit of Steem Power with Ethereum which was sitting in my MyEtherWallet.

I did it directly:

1. generated a receiving address on SteemIt Transfers page
2. executed the transaction on MyEtherWallet
3. waited a bit :)

The transaction came through without a hick with ether gas deducted automatically.

Thanks again for a gentle kick in my butt which your post provided :)
