Why does the use of #strike cause a linebreak?

Questions
1

The following line causes a linebreak?

  - #strike([09. Juni 2025]) Pfingstmontag

“Pfingstmontag” ist indented below the date, which is a list item.

An even more minimal reproduction is the following:

- #[09. Juni 2025] Pfingstmontag

A hint that something’s wrong here is that the text says “9. Juni”, not “09. Juni”. Apparently, the content block #[...] or alternatively strike() causes the 09. to be interpreted as the start of an enumerated list! Maybe someone from the team can comment on whether that is considered a bug or not.

There are a few ways you can prevent this from happening:

- #strike[\09. Juni 2025] Pfingstmontag
- #strike("09. Juni 2025") Pfingstmontag

Personally, I would use the datetime type combined with the datify package to localize month names:

#import "@preview/datify:0.1.2": custom-date-format
#set text(lang: "de")

#let format-date(date) = context custom-date-format(date, "DD. Month YYYY", text.lang)

- #strike(format-date(datetime(year: 2025, month: 12, day: 9))) Pfingstmontag

// or, if you type the dates manually and don't want to use the long datetime constructor:
#let format-date(date) = {
  let date = toml.decode("date = " + date).date
  context custom-date-format(date, "DD. Month YYYY", text.lang)
}

- #strike(format-date("2025-12-09")) Pfingstmontag

Great answer. You got the eyes of an eagle! It did not occur to me that it could have been the start of an enumeration. In ‘regular’ markup I might have caught it but as typst uses ‘+’ I did not think of it. Although I had read at some time that enumerations could be skipped/restarted etc.
