AFAIK, mempool.space added that feature not so long ago.
But it's easy to miss because the partial match addresses don't always show, the firstbits has to be clicked sometimes.
Another one is walletexplorer, but it's more of an address-matching tool than a blockexplorer.
It's also limited to one result even if there are two or more matches.
Thanks. That did the trick. Now I can look at the coins I lost the keys to many years ago.

Trying to decide if I should attempt to repair an old hard drive to try and recover the coins or not. Looks like I should probably check into it. I’ve been hanging onto it for more than a decade but I think the time may have finally come.
