docs: If an {@link #onErrorContinue(BiConsumer)} variant has been used before, reverts to the default
  'STOP' mode where errors are terminal events. It can be used for easier scoping of
  the on next failure strategy or to override the inherited strategy in a sub-stream
  (for example in a flatMap). It has no effect if {@link #onErrorContinue(BiConsumer)} has not
  been used.
  
  @return a {@link Flux} that terminates on errors, even if {@link #onErrorContinue(BiConsumer)}
  was used before
