Config; just biome init
Situation: try disabling the first font in your font-family (system-ui is not so welcomed in Japanese)

Prettier can guess this background and work as intended, but Biome does not.

Before:

[lang]:lang(ja) {
  font-family: /* system-ui,*/ Hiragino Sans, sans-serif;
}

Prettier/Expected:

[lang]:lang(ja) {
	font-family: /* system-ui,*/
		Hiragino Sans,
		sans-serif;
}

Biome:

[lang]:lang(ja) {
	/* system-ui,*/ font-family:
		Hiragino Sans,
		sans-serif;
}

You have only to uncomment out the comment to restore the previous state.
