Describe the issue:

When creating a targets workflow using tarchetypes::tar_assign , items that should be in the outline pane (thanks for the recent work on parsing outline items!) aren't.

Steps to reproduce the issue:

Create an R file with these contents (and tarchetypes installed, maybe?)

# this is an item -----
source("./packages.R")

## and this is another -----
var1 = rnorm(200)

tar_assign(
{
  # another variable -----
  var2 = rnorm(400) |>
    tar_target()
}
)

var3 = function(){
  # does this work? -----
  something = "crap"
}

tar_plan(
  # what about this ------
  var4 = tar_target("crap")
)

Expected or desired behavior:

Expected to see in the outline:

this is an item
and this is another
{} var1
another variable
{} var2
var3
  does this work
  {} something
what about this
{} var4

What I see

var2, another variable, what about this and `var4} are missing from the outline.

this is an item
and this is another
{} var1
var3
  does this work
  {} something
