Outlier detection vignette chunk

x <- x %>%
  group_by(geo_value) %>%
  mutate(
    outlier_info = detect_outlr(
      x = time_value,
      y = cases,
      methods = detection_methods,
      combiner = "median"
    )
  ) %>%
  ungroup() %>%
  unnest(outlier_info)

yields

Why? Is this indicative of a bug, or are we just missing some tweak to avoid this spam?
