autoplot show_gap on fbl_ts errors

(In the posit::conf 2023 workshop)

brick_fit <- aus_production |>
  filter(!is.na(Bricks)) |>
  model(
    `Seasonal_naïve` = SNAIVE(Bricks),
    `Naïve` = NAIVE(Bricks),
    Drift = RW(Bricks ~ drift()),
    Mean = MEAN(Bricks)
  )

brick_fit |>
  forecast(h = "5 years") |>
  autoplot(filter(aus_production, Quarter > yearquarter("2000 Q1")), level = 50)

This works, but adding show_gap=FALSE fails with

brick_fit |>
  forecast(h = "5 years") |>
  autoplot(filter(aus_production, Quarter > yearquarter("2000 Q1")), level = 50, show_gap = FALSE)
# Error in `retain_tsibble()`:
# ! The result is not a valid tsibble.
# ℹ Do you need `as_tibble()` to work with data frame?
# Run `rlang::last_trace()` to see where the error occurred.

Oddly enough, very similar models built on slightly different datasets do work:

hh_fit <- hh_budget |>
    model(
    `Naïve` = NAIVE(Wealth),
    Drift = RW(Wealth ~ drift()),
    Mean = MEAN(Wealth)
  )
hh_fit |>
  forecast(h = "5 years") |>
  autoplot(hh_budget, level = NULL, show_gap = FALSE)

aus_fit <- aus_retail |>
  filter(grepl("Clothing", Industry), grepl("South", State)) |>
  model(
    `Seasonal_naïve` = SNAIVE(Turnover),
    `Naïve` = NAIVE(Turnover),
    Drift = RW(Turnover ~ drift()),
    Mean = MEAN(Turnover)
  )
aus_fit |>
  forecast(h = "2 years") |>
  autoplot(
   filter(aus_retail, grepl("Clothing", Industry), grepl("South", State), Month > yearmonth("2010 Jan")),
   level = NULL, show_gap = FALSE)

I'm really enjoying the class, thank you!
