Why is :box not getting the current background color?. It doesn't even work if I setq a variable with the color hardcoded, but if I set the hex color as a literal it works perfectly. If I evaluate manually the sexp (face-background 'default) it returns the right color #1E1C31 ( a dark color, but if you notice on the screenshot is setting a bright color ).
(set-face-attribute 'tab-bar-tab-inactive nil
:family "Cascadia"
:foreground (face-foreground 'default)
:background (face-background 'default)
:height 1.3
:slant 'italic
:box '(:line-width 9 :color (face-background 'default))
)
In my opinion my question is not exactly the same as this one: https://emacs.stackexchange.com/a/7487/7006
In both cases the solution could be solved creating a list, but in this case as @db48x explained there's an alternate solution with quasiquoting that the other answers discourage the use.
