`group_tt()`: multiple `i` entries is unintuitive

tt(head(iris)) |>
    group_tt(i = list("Blah" = 2, "Hello" = 3)) |>
    print("markdown")

I have a question related to this. I tried to have a group at i = 0 and got an error. How can I have a group that starts with the first line of the table?

Edit: I should add that I'm using Typst as output format. Looking at the markdown example above I'm wondering if there's not something going on there. I'll do some tests when I have the chance.

I can confirm that there is something unusual going on:

---
format: typst
---

```{r}
#| output: asis
library(tinytable)
tt(head(iris)) |>
  group_tt(i = list("Blah" = 1)) |>
  print("markdown")

library(tinytable)
tt(head(iris)) |>
  group_tt(i = list("Blah" = 1))

The markdown places the *Blah* before the first line, whereas in Typst it's placed  after the first line and the last line gets pushed down.
