For reproduce the tailwind-jit doesn't watch changes in @layer (Angular)
With angular cli + tailwindcss
With npx ng-tailwindcss-jit (https://github.com/apvarun/ng-tailwindcss-jit)
Run npm install
Run npm run start
Try to modify something in 's-text-primary.scss'
In @layer section, it won't take effect unless re-start the dev server
Out @layer it works fine ...
