`assignment_linter(allow_trailing = FALSE)` fails when comment in brace

[ashbaldry]

I have found an issue with the new allow_trailing argument for assignment_linter where if there is a comment somewhere in a set of braces, then it will flag all of the assignments in the braces

text <- 'testthat::test_that("app ui", {
  ui <- appUI()
  golem::expect_shinytaglist(ui)
  # Check that formals have not been removed
  fmls <- formals(appUI)
    
  for (i in "request") {
    testthat::expect_true(i %in% names(fmls))
  }
})

testthat::test_that("app server", {
  server <- appServer
  testthat::expect_type(server, "closure")
  # Check that formals have not been removed
  fmls <- formals(appServer)
  for (i in c("input", "output", "session")) {
    testthat::expect_true(i %in% names(fmls))
  }
})'

lint(
  text = text,
  linters = assignment_linter(allow_trailing = FALSE)
)

Expected: no lints
Actual: 4 lints
