Research direction

Start with the reproduction in the issue: compare a .Rprofile containing a .First() function with one containing a bare assignment, and consult discussion #6394 for context. Trace how Positron starts an R session and loads .Rprofile; done means code inside .First() runs and defines x as expected.

Description

bug lang: r support

In https://github.com/posit-dev/positron/discussions/6394 we have a report of code not getting run if it is in the .First() function in .Rprofile.

For example, if your .Rprofile has this in it:

.First <- function(){
    x <- 1
}

that variable is not actually defined.

If you have x <- 1 in your .Rprofile but "bare" then it does get executed.
