In Griffiths Introduction to electrodynamics it is said that Newton's third law is not valid in electrodynamics, but, in the example given, the it does not consider the retarded values for the fields and looks at the contradiction only on the magnetic force.

Just putting the books example: Two positive charges are moving along axes x and y towards the origin. The electric forces satisfy Newtons 3rd law, but the magnetic don't.

Question: Does Newton's third law hold for Lorenz force with appropriate retarded fields?

Is Newton's third compatible with retarded Lorentz force?
