Reproduction URL

https://github.com/artaommahe/tailwind-intellisense-multiple-configs

• clone
• npm install
• npm run dev
• see that everything looks like expected
  
• open NewDesignComponent and Button components in vscode
• see that colors are wrong and for some tokens there is no autocompletion and highlighting

border should be red, bg black, text white, p-4 bigger, etc

same with colors, secondary border and p-2 are not recognized

Describe your issue

In our project we're on a way of slow migration from the old messy design system (set in the main tailwind config) to the new shinny one (set in another config). While tailwind itself recognizes both configs and there corresponding content files properly and all the colors and other values are correct in the browser, the vscode extension struggles here and sometimes shows correct (new) values for new-design/* and ui-kit/* components, sometimes not. In the reproduction repo it even always shows the old values for some reason.
