Rugs disappear in calibration plots when using `.by` argument

[abichat]

The problem

When using cal_plot_breaks(), cal_plot_windowed() or cal_plot_logistic() with the .by argument, the rugs disappear from the plot, even with include_rug = TRUE.

Reproducible example

library(dplyr)
library(probably)


packageVersion("probably")
#> [1] '1.1.1'

segment_logistic <-
  segment_logistic %>% 
  mutate(group = sample(c("A", "B"), n(), replace = TRUE))

cal_plot_breaks(
  segment_logistic,
  Class,
  .pred_good
)

cal_plot_breaks(
  segment_logistic,
  Class,
  .pred_good,
  .by = group, 
  include_rug = TRUE
)

Thanks for considering this issue, and for your work on probably!
