`child_labels` ignored by `split_rows_by_cutfun()`

child_labels = "hidden" works with split_rows_by(), but is ignored by split_rows_by_cutfun().

Works as expected with split_rows_by()

dat <- DM
dat$AGEGRMED <- ifelse(DM$AGE <= median(DM$AGE), "Younger", "Older")

lyt <- basic_table() |>
  split_rows_by("AGEGRMED", child_labels = "hidden") |>
  analyze("BMRKR1", mean, format = "xx.xx")

tbl <- build_table(lyt, dat)
tbl
all obs
——————————————
mean    6.09
mean    5.65

child_labels is ignored by split_rows_by_cutfun()

cutfun <- function(x) {
  cutpoints <- c(min(x), mean(x), max(x))
  names(cutpoints) <- c("", "Younger", "Older")
  cutpoints
}

lyt2 <- basic_table() |>
  split_rows_by_cutfun("AGE", cutfun = cutfun, child_labels = "hidden") |>
  analyze("BMRKR1", mean, format = "xx.xx")

tbl2 <- build_table(lyt2, dat)
tbl2
all obs

It is important that child_labels = "hidden" is not ignored, particularly when the afun creates the row label.

The label_pos = "hidden" is also ignored by split_rows_by_cutfun()....

Start at the split_rows_by_cutfun() entry point and compare its handling of child_labels and label_pos with split_rows_by(). Reproduce the supplied AGE and cutfun examples, then verify that both options are honored, including when the afun creates the row label.
