Hello E2E,
Could you verify the state of the SCL and SDA pins when UCD9081 is not powered (high impedance)?
Thanks!

The pin should be in high impedance state but if the device is not powered and a voltage is applied to the pins, ESD diode will conduct, and current will flow from the pin to VCC cap.
