Reproduce the issue by connecting the Extension to the MetaMask developer faucet at the URL in the report, using Chrome on macOS with version 12.8.0. Compare the jazzicon shown in the Extension with the one shown by the faucet; done means the account displays consistently in both places, with the relevant implementation location and verification steps identified.
