      Description

      ARROW-8899 collects R attributes from the columns of a data.frame (including recursively in data frame columns), adds them to arrow schema metadata, and restores them when pulling a data frame into R. However, any attributes on the outer data frame itself are not preserved. These are lost in some autosplice magic code before AddMetadataFromDots can collect it.
