Configuration

import js from "@eslint/js";
import sveltePlugin from "eslint-plugin-svelte";
import svelteParser from "svelte-eslint-parser";
import tseslint from "typescript-eslint";

export default tseslint.config(
  js.configs.recommended,
  ...tseslint.configs.recommended,
  ...sveltePlugin.configs["flat/recommended"],
  {
    files: ["**/*.svelte", "*.svelte"],
    languageOptions: {
      globals: {
        window: false,
        console: false,
      },
      parser: svelteParser,
      parserOptions: {
        parser: {
          ts: "@typescript-eslint/parser",
        },
        extraFileExtensions: [".svelte"],
      },
    },
    rules: {
     'svelte/no-top-level-browser-globals': 'error',
    }
  }
);

<script>
  import { browser } from '$app/environment';

  const notification = browser
    ? 'Notification' in window 
    : false

  if (notification) console.log('hi');
</script>

{#if browser}
  <div>
    <pre>Notification: {'Notification' in window}</pre>
  </div>
{/if}

What did you expect to happen?

No errors to be reported since the access is guarded by {#if browser}

What actually happened?

Unexpected top-level browser global variable "window".
