Coinbase sended btc when unconfirmed

[t0muchewe]

Hello,

I transfered some btc from electrum to coinbase, it shows on my coinbase account "pending"
When i check the trans id on blockchain it shows that the address i sended to (my coinbase address) is already sending it to another address while the first transaction is still unconfirmed.
I did not send anything from coinbase to another address yet cuz its not possible but it appears they sended it.

Is this supposed to be?

thanks in advance

edit-
So it got confirmed and btc is correct, although they sended it from my address to another it still shows the correct ammount of btc in coinbase.
But they sended it with a way to high fee so how do they make a profit from this then?
