foreground color displays as background color?

[hozza]

Sorry for several creating issues at once, I thought each issues as a separate ticket may be easier to manage. :nerd_face:

Maybe I've missed something obvious, but applying a foreground color (in the theme override file) seems to apply it to the background?

{
  "name": "SECTION COMMENTS",
  "scope": "comments.section",
  "foreground": "#896afc",
  "background": "var(--background)",
},
