rename(Pair<String, String>) assigns new names in the wrong order

[koperagen]

Given:

val df = listOf(
  Triple(1, 10, 0.1),
  Triple(2, 20, 0.2)
).toDataFrame()
  .rename("first" to "id", "second" to "df_count", "third" to "df_ratio")

This

df.rename(
  "df_ratio" to "ratio_df",
  "df_count" to "count_df"
)

Should be id, count_df, ratio_df, but now is id, ratio_df, count_df, so columns are assigned a new name in the order they occur in the dataframe
