Very true but the RF is still in the oil "dielectric" from the coax
connector to the hot end of the resistor.
Not the same at all.
Loss tangent is meaningless in the dummy load application because impedance
is low (weak electric field). There is very little displacement current
compared to current into the resistor.
Loss tangent means everything in a capacitor in a coupling or tuning system,
because displacement current is as high as or higher than the terminal
current.
