Parsing error when </script> is present in a string literal of a component script

[sfriedel]

Before You File a Bug Report Please Confirm You Have Done The Following...

• I have tried restarting my IDE and the issue persists.
• I have updated to the latest version of the packages.

What version of ESLint are you using?

8.47.0

What version of eslint-plugin-svelte are you using?

2.32.4

What did you do?

When a string literal in a svelte component script contains "</script>" the eslint plugin produces a parser error.

Configuration

module.exports = {
	root: true,
	extends: [
		'eslint:recommended',
		'plugin:@typescript-eslint/recommended',
		'plugin:svelte/recommended',
		'prettier'
	],
	parser: '@typescript-eslint/parser',
	plugins: ['@typescript-eslint'],
	parserOptions: {
		sourceType: 'module',
		ecmaVersion: 2020,
		extraFileExtensions: ['.svelte']
	},
	env: {
		browser: true,
		es2017: true,
		node: true
	},
	overrides: [
		{
			files: ['*.svelte'],
			parser: 'svelte-eslint-parser',
			parserOptions: {
				parser: '@typescript-eslint/parser'
			}
		}
	],
	globals: {
		// workaround for lack of $$Generic support in svelte-eslint-parser.
		// See https://github.com/sveltejs/svelte-eslint-parser/issues/306
		$$Generic: 'readonly'
	}
};

<script>
	const src = '</script>'
	console.log(src)
</script>

<h1>Example</h1>

This is Svelte compiler's issue.
Not ESLint issue.

@baseballyama thanks and sorry for the noise. Apparently this is a known behaviour in svelte that won't be changed.
