fonts.extras not loading.

[darkralts]

fonts.extras = [
    { family = "Sarasa Mono Slab J" }
]

fonts here not loading at all if i do this.

only way i have gotten fonts to load is here:
[fonts]
family = "Iosevka Term Slab"

but i dont want to change or overwrite that, i just want the Japanese Sarasa mono slab font to load as well. as a fallback, a 2nd font.

hi i figured a different syntax from the website works

[[fonts.extras]]
family = "Sarasa Gothic J"
