When adding type_hline() or type_vline() to a plain faceted tinyplot() (i.e., not via by), then the lines are only added in the first panel:
tinyplot(bill_len ~ flipper_len, facet = ~ species, data = penguins)
tinyplot_add(type = type_hline(44))
tinyplot_add(type = type_vline(200))

Interestingly, the same code works for a facet = "by" plot:
tinyplot(bill_len ~ flipper_len | species, facet = "by", data = penguins)
tinyplot_add(type = type_hline(44))
tinyplot_add(type = type_vline(200))

I didn't try to dig into this, yet. Maybe it's also related to the color recycling from #410 ?
