That does not happen in the real world.

Present a photo of scoped waveforms of a system containing a gap which
can perform this trick with no breakout from the terminal and I will
be forever silent. The most detailed investigations I have done
suggest you cannot do so. To then talk of magical voltage rises
on quenching this way smacks of armchair thinking.
