beaconcha.in API response is out of sync with web UI

[gg718]

Example Holesky validator:

• 0x91d82644e98c3ed65acc6d4f795c13ad40a7067fdad5fb24193a5fc3dd48dfe6a8c0a82a944faf81b341caa0a4f723f9

At the time of writing, this validator has been offline for ~3 days. The UI correctly shows the last successful attestation at slot 3385673 (correct):

However, the API response is reporting this validator as active_online (rather than active_offline) with the last successful attestation at slot 3407476 (incorrect):

    "total_withdrawals": 637531391
  }
}

If I had to estimate, I would say this issue started within the last week or so.
