As you can see, if you click on JSDoc part of tree, @errors is given its own tag, even thought it is inside

💻 Code

interface SomeThing {
		/**
		 * An object containing zero or more aliases used to replace values in `import` statements. These aliases are automatically passed to Vite and TypeScript.
		 *
		 * ```js
		 * // @errors: hello
		 * /// file: svelte.config.js
		 * /// type: import('@sveltejs/kit').Config
		 * const config = {
		 *   kit: {
		 *     alias: {
		 *       // this will match a file
		 *       'my-file': 'path/to/my-file.js',
		 *
		 *       // this will match a directory and its contents
		 *       // (`my-directory/x` resolves to `path/to/my-directory/x`)
		 *       'my-directory': 'path/to/my-directory',
		 *
		 *       // an alias ending /* will only match
		 *       // the contents of a directory, not the directory itself
		 *       'my-directory/*': 'path/to/my-directory/*'
		 *     }
		 *   }
		 * };
		 * ```
		 *
		 * > The built-in `$lib` alias is controlled by `config.kit.files.lib` as it is used for packaging.
		 *
		 * > You will need to run `npm run dev` to have SvelteKit automatically generate the required alias configuration in `jsconfig.json` or `tsconfig.json`.
		 * @default {}
		 */
		alias?: Record<string, string>;
}

🙁 Actual behavior

@errors in the code snippet was marked as a JSDoc tag

🙂 Expected behavior

@errors is inside a code snippet, should not be parsed as a JSDoc tag at all

Reproduce the issue using the supplied playground link and the interface/JSDoc example in the report. Trace the JSDoc parsing path for fenced code blocks and verify that @errors inside the block is not emitted as a tag, while the actual @default tag remains recognized.
