It would be open, period.

ESR = effective (or equivalent) series resistance.

Frankly, never heard of stuffing a bunch of small ones
in series in the old can.
"Edison effect" probably refers to darkening of the glass, which doesn't necessarily imply the tube is bad. But if it runs 'way hot to the touch after a few minutes, it would likely be on the verge of failing. That's the old school "life test" of a HV rect.
