FWIW:
Most energy storage capacitors should not be directly shorted. Discharged by a suitable power resistor. Such an energy dump can cause disassociation of metalizing or opening an internal link to the terminals. The separation of metalizing can cause noise issues in sensitive circuits as these isolation's of metalizing connect and disconnect randomly.
