Everything was discovered in XIX (for the radio):

But then later it was found that the first discoveries were not
entirely correctly described.

"The electrical waves produced by the oscillations at A traveled along the
wires and were reflected at the far ends. Lodge knew that the longer spark
at B3 was due to what he called the "recoil impulse" or "recoil kick" at the
end of the wires where the waves were reflected.[4] At spark gap B3 both the
incident wave and the reflected wave had their maximum values and were in
phase. This produced a voltage twice as large as the voltage at spark gap A.

Is it still true?

A reflected wave along a nonterminated transmission line will result in
doubled voltage at the open end.

If yes, than you must admit that the leakage must be stronger at "recoil
kick" when the voltage is doubled.
"So there is the unsymmetrical flow of electrons." Do you agree?

But here you are talking complete hogwash again. The effect you describe
above has nothing to do with leakage or unsymmetrical flow of electrons.
