VS Code Extension CSS Diagnostic Setting not respected

Describe the bug Using custom css syntax VS Code Extension throws error svelte(css-syntax-error), with extension setting set to: "svelte.plugin.css.diagnostics.enable": false

{
	"resource": "/c:/.../tests/assets/input/windi/case-03.svelte",
	"owner": "_generated_diagnostic_collection_name_#0",
	"code": "css-syntax-error",
	"severity": 8,
	"message": "Semicolon or block is expected\n\nIf you expect this syntax to work, here are some suggestions: \nIf you use less/SCSS with `svelte-preprocess`, did you add `lang=\"scss\"`/`lang=\"less\"` to you `style` tag? If you use SCSS, it may be necessary to add the path to your NODE runtime to the setting `svelte.language-server.runtime`, or use `sass` instead of `node-sass`. \nDid you setup a `svelte.config.js`? \nSee https://github.com/sveltejs/language-tools/tree/master/docs#using-with-preprocessors for more info.",

	"startLineNumber": 11,
	"startColumn": 28,
	"endLineNumber": 11,
	"endColumn": 28
}

To Reproduce note: it is not scss or sass syntax. It is custom syntax

<style>
  .custom {
    background: green;
  }
  :global(.me) {
    background: yellow;
  }
  a {
    @apply text-black hover:text-emerald-400;
  }
  :global(div) {
    @apply bg-light-800 dark:bg-dark-600;
  }
</style>

Expected behavior "svelte.plugin.css.diagnostics.enable": false should disable error & warnings for wrong css syntax

Screenshots

System (please complete the following information):

• OS: Windows
• IDE: VSCode
• Plugin/Package: Svelte for VSCode 105.0.0

Additional context not sure, but I might guess of regression here. Since it worked in the past.

no. as said earlier. It seems that the order get’s confused on my preprocessors… Thanks for the hint

There are many things going on at once in this preprocess config. I guess that windi is responsible for doing the style transformation. Does the error occur if you apply only this preprocessor? Like

import { windi } from 'svelte-windicss-preprocess'

export default {
  preprocess: windi({
      silent: false,
      configPath: "windi.config.js",
      devTools: {
        enabled: false
      }
    })
}
