dbplyr cyclic namespace dependency detected: does it unload correctly?

[raffaem]

I am unable to unload the tidyverse namespaces after using dbplyr.

Did I find a bug in dbplyr? Does it unload correctly?

library(tidyverse)

con <- DBI::dbConnect(RSQLite::SQLite(), ":memory:")
copy_to(con, mtcars)
DBI::dbDisconnect(con)

unloadNamespace("tidylog")
unloadNamespace("tidyr")
unloadNamespace("purrr")
unloadNamespace("tidyverse")
unloadNamespace("ggplot2")
unloadNamespace("readr")
unloadNamespace("dbplyr")
unloadNamespace("dplyr")
unloadNamespace("tibble")
unloadNamespace("stringr")
unloadNamespace("forcats")
unloadNamespace("magrittr")

library(tidyverse)

results in:

Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : 
  cyclic namespace dependency detected when loading ‘dplyr’, already loading ‘dbplyr’, ‘dplyr’, ‘ggplot2’
