cli R package progress bars not showing if multiple progress bars created in quick succession

[gacolitti]

If I create multiple {cli} progress bars in quick succession, only the first progress bar is shown. However, if I add a short timer with Sys.sleep(0.2), all progress bars are shown:

options(cli.progress_show_after = 0)

fun <- function(step) {
  cli::cli_progress_bar(
    clear = FALSE
  )
  cli::cli_progress_update(inc = 0)
  cli::cli_progress_done()
}

fun_sleep <- function(step) {
  cli::cli_progress_bar(
    clear = FALSE
  )
  cli::cli_progress_update(inc = 0)
  cli::cli_progress_done()
  Sys.sleep(0.2)
}

purrr::walk(1:3, function(x) fun(x))

purrr::walk(1:3, function(x) fun_sleep(x))

How do I show all progress bars without needing to use Sys.sleep(0.2)?

Seems like a bug to me.

I'm finding this to be the case for me as well. Worked perfectly on R v4.2.1 on my M1 mac, but after updating to 4.3 on my M1 it won't display anything.
