It is true of all capacitors (CRTs are intentional capacitors, after all) designed for and subjected to sufficiently high voltage. It's referred to as dielectric absorption, and is why HV caps ship from the factory with the leads shorted. I have a 4.7 uF tens-of-kV capacitor in the shop for reasons. The shorting jumper got knocked off once while moving stuff past it, and I noticed it the next day. By that point, it had accumulated enough charge to register over 200V on a Simpson 260 VOM (not a high impedance meter). I don't know if that was accumulated static charge or from dielectric absorption. Thanks, Jonathan
