`#pause` may hide parts of the template (or: we need a way to reset the pause counter)

Suppose we have a template like follows:

#let slide(title: "", content) = {
  let content = {
    grid(
      columns: (1fr, 3.5em),
      // Title and content
      grid(
        rows: (3em, 1fr),
        text(size: 25pt, title),
        text(size: 18pt, content),
      ),
      // Sidebar
      grid(
        rows: (1fr, 2em),
        [],
        text(size: 14pt, logic.logical-slide.display()),
      ),
    )
  }

  logic.polylux-slide(content)
}

If we now use #pause in such a slide, the sidebar of the template will be hidden on all but the last subslide.
To fix this, we would need some sort of mechanism to reset or scope the effect of #pause.
I tried wrapping the last grid in an only((:)) block, but this didn't work.

Very true. I think pause should work differently in the future and follow Typst scopes and be less hacky.

Workaround for now:

#let unhide(it) = {
  show hide: x => x.body

  it
}

#let slide(title: "", content) = {
  // [..]
  // Sidebar
  unhide(grid(
    // [..]
  ))
  // [..]
}
