Alignment problem on #outline

[jolly sparrow]

Hi, I try to display a table of contents this way:

#show outline.entry.where(
  level: 1
): it => {
  v(12pt, weak: true)
  strong(it)
}

#outline(depth: 2, indent: auto, title: [Sommaire])

As you can see in the image, the titles are not aligned. Is it something I can change or is that a known bug? (I've seen posts on the web stating that)

that seems like a bug specific to roman numbering it seems

in the meantime, you can just specify 1em instead
