Analysis:  (yours)

A charged capacitor plate experiences Force and Pressure and has an increase
in Mass. The Force, Pressure and Mass  decrease as the capacitor discharges.

Hmmm.   I could swear you said the charged capacitor plate had an increase
in Mass.
Now I hear you say there is a volumetric E field mass.  Just a subtle
switch.

When you blow up a balloon do you say that the balloon has increased mass?
(Clearly the membrane does not increase mass!)

Not obfuscation, just subtelties in language.

Sorry about the confusion!
