R's native placeholder not recognised in chained `data.table` steps #3749

Thanks for the new IDE. I normally use R's native placeholder _ in chained data.table steps. However, in the below step, symbols are not recognised.

The diagnostics problem here may be specific to how _ is used in data.table. This code, for example, has correct diagnostics:

mtcars |> lm(mpg ~ cyl, data = _)

Something like below also raises error using data.table, but was suggested by the code completion.
