toolbox.current-section is empty in header for first page

[luxzeitlos]

Hello

it seems that when using #toolbox.current-section in the header of the first page is empty, even when set before calling #slide.
It however works for consecutive slides, or when #toolbox.register-section is called before #set page.

So this does not work as expected:

#import "@preview/polylux:0.4.0": *

// #toolbox.register-section[X] // This here actually works, and is displayed on the first slide.

#set page(
  header: toolbox.current-section,
  paper: "presentation-16-9",
)

#toolbox.register-section[Content A] // this does *NOT* work, but I expected it to work

#slide[
  Content A
]

#toolbox.register-section[Section B]
#slide[
  Content B
]

Interesting... I guess interactions with #set page always lead to trouble 😅 I think it's not so much of a problem in most cases since one would often have a title slide without a section anyways.
