decomposition result of multiAirlineDecomposition

[AQLT]

I think there is an error in the output of the decomposition of multiAirlineDecomposition() (more exported components than expected)
https://github.com/rjdemetra/rjd3highfreq/blob/010dd15052736669018b9dd8c0ed58ff1220a2f3/R/jd3_fractionalairline.R#L298-L301
I think the irregular is the last object but then I don't know what is the penultimate.
Moreover, I don't find the SA series using y and the seasonal component

amb.multi <- rjd3highfreq::multiAirlineDecomposition(
  y = forecast::taylor,
  periods = c(2 * 24, 2*24*7),
  log = FALSE, ndiff = 2)
decomp <- amb.multi$decomposition
# Last name not defined
names(decomp)
#> [1] "y"      "y_time" "sa"     "t"      "s_48"   "s_336"  "i"      NA
all.equal((decomp$t + decomp$i), decomp$sa)
#> [1] "Mean relative difference: 0.004231776"
all.equal((decomp$t + decomp[[8]]), decomp$sa)
#> [1] TRUE
# Should it be true ?
all.equal((decomp$y - (decomp$s_48 + decomp$s_336)), decomp$sa)
#> [1] "Mean relative difference: 0.004299653"
