I'm trying to make the slide background transparent when exporting to png. it doesn't work.

section {
    background-color: transparent;
    width: 1920px;
    height: 1080px;
}

:root {
    background-color: transparent;
}

marp --theme custom.css test.md -o test.png

return await page.screenshot({ clip, type: 'png' })

I've tried using omitBackground: true but it will not yet render PNG with transparency.
