row column wrong in problems() with read_fwf

[acdoering]

Row column in data frame returned by problems() is wrong on results from read_fwf():

writeLines("15AB12\n161013\n161013\n17AC14\n18AB15", "testdata.txt")
x <- readr::read_fwf("testdata.txt", 
  col_types = "iii",
  col_positions = readr::fwf_widths(c(2,2,2), col_names = c("a", "b", "c")))
readr::problems(x)
# wrong, rows 1,2,2 with issues in col2 

# compare with read_csv():
writeLines("15,AB,12\n16,10,13\n16,10,13\n17,AC,14\n18,AB,15", "testdata.csv")
y <- readr::read_csv("testdata.csv", 
                     col_types = "iii",
                     col_names = c("a", "b", "c"))
readr::problems(y)
# correct, rows 1,4,5 with issues in col 2    

using R version 4.1.0, readr 2.1.3, vroom 1.6.4
