Add icon to indicate when an address has received funds from itself

Given that most addresses never have an output to themselves it is easy to make the false assumption that the 'confirmed recieved' value is the total amount into a donation address.

In the case if the CoinJoin Bounty Address https://blockstream.info/address/3M8XGFBKwkf7miBzpkU3x2DoWwAVrD1mhk this *user error* led me to falsely conclude that half the funds had been spent!

Perhaps it would be useful to have an icon to indicate when an address has an output to itself to help avoid this user error.
