Wrong title and subtitle in (at least) theme.simple

[f3fora]

The results shown in the picture at
https://touying-typ.github.io/docs/start
is different from the one produce by the shown code.

The following code produces slides where the title is First Slide and the small text above it is also First Slide and not Title

#import "@preview/touying:0.5.2": *
#import themes.simple: *

#show: simple-theme.with(aspect-ratio: "16-9")

= Title

== First Slide

Hello, Touying!

#pause

Hello, Typst!

It will be fixed in the next version and you can use #show: simple-theme.with(aspect-ratio: "16-9", header: utils.display-current-heading(level: 1)) first.
