Size and Length in Environment Pane is 0

I'm experiencing the error when using dplyr::mutate where a formerly "finite" object with a triangle marker "disappears" with no visible marker and size = 0B and length = 0.

The missing blue disclosure arrow problem was discussed quite a bit over here (despite the topic title, it doesn't turn out to have anything to do with tibble vs data frame, btw):

Environment:Data: data.frames expand with blue arrow but tbl_dfs don't

Open a simple csv with a <- read.csv(file.csv), "data.frame" and again with b <- tidyverse::read_csv(file.csv) "spec_tbl_df" "tbl_df" "tbl" "data.frame" In the Environment tab, 'a' can be expanded with the blue arrow, 'b' cannot, despite both being simple square tables with named columns, each of which has a class and some data. Please could this be added/fixed? Thanks edit: it may not be 100% as simple as this since my reproducible example can be opened just fine. Yet i've recently found lots of objects don't expand and I'm not sure why, the only seemingly common thread being my recent attempts to adopt tidyverse practices.

Drawing from that thread, I'm curious… for people experiencing this problem, what happens if you run .rs.hasAltrep() on one of the objects showing the wrong size and length? Is it always TRUE? (If so, sounds like trying out the recently released Preview version v1.2.1565-5 might help).
