Based on my dislexic spelling of dissolve above I am compelled to say it is because magnesium is more affectionate with water than platinum and less affectionate than lithium or potassium. Lithium and potassium are far more reactive with water than magnesium. However, I do recall reading that lithium is indeed adsorbed by palladium and does diffuse through it during electrolysis, though id diffuses slowly and thereby diminshes the diffusion rate of hydrogen.
