Think these are so called gimmick capacitors you are describing. They only connect at one end and are only a few picofarads of capacitance. Zenith did this on some of their radios. A small amount of the oscillator signal is coupled back to the RF input lead of the mixer stage. It was negative feedback that was important at shortwave frequencies.
