Error on View() of data.table with list column with numeric values

RStudio IDE

RStudio View() can inspect a data.table/data.frame with list column. However with the recent preview version 1.2.907, list column with numeric values get an error.

test_dt_1 <- data.table(id = 1:5)
test_dt_1[, list_col := list(list(letters[1:5]))]
test_dt_1$list_col
View(test_dt_1)

test_dt_2 <- data.table(id = 1:5)
test_dt_2[, list_col := list(list(1:5))]
test_dt_2$list_col
View(test_dt_2)

The 2nd example will have this error:

Error in is.finite(x[[idx]]) : 
  default method not implemented for type 'list'

R version 3.5.1 (2018-07-02)
Platform: x86_64-apple-darwin15.6.0 (64-bit)
Running under: macOS High Sierra 10.13.6

Works in the daily build so it looks like its been fixed:

it does same for me with

> View(tibble::data_frame(x = purrr::rerun(4,matrix(1:4,2,2))))
Error in is.finite(x[[idx]]) : 
  default method not implemented for type 'list'
