[vite-node] error transforming template literals with source map magic string

[Tanimodori]

Describe the bug

vite-node will transform the following code

export function foo(src: string): string {
  return `//# sourceMappingURL=data:application/json;base64,${src}`;
}

into

// /home/projects/vitest-dev-vitest-dq6zze/foo.ts
function foo(src) {
  return `
}
Object.defineProperty(__vite_ssr_exports__, "foo", { enumerable: true, configurable: true, get(){ return foo }});

//# sourceMappingSource=vite-node
//# sourceMappingURL=data:application/json;charset=utf-8;base64,eyJ2ZXJzaW9uIjozLCJtYXBwaW5ncyI6IkFBQU8sU0FBUyxJQUFJLEtBQXFCO0FBQ3ZDLFNBQU8scURBQXFEO0FBQzlEO2lIQUFBIiwibmFtZXMiOltdLCJzb3VyY2VzIjpbIi9ob21lL3Byb2plY3RzL3ZpdGVzdC1kZXYtdml0ZXN0LWRxNnp6ZS9mb28udHMiXSwic291cmNlc0NvbnRlbnQiOlsiZXhwb3J0IGZ1bmN0aW9uIGZvbyhzcmM6IHN0cmluZyk6IHN0cmluZyB7XHJcbiAgcmV0dXJuIGAvLyMgc291cmNlTWFwcGluZ1VSTD1kYXRhOmFwcGxpY2F0aW9uL2pzb247YmFzZTY0LCR7c3JjfWA7XHJcbn1cclxuIl0sImZpbGUiOiIvaG9tZS9wcm9qZWN0cy92aXRlc3QtZGV2LXZpdGVzdC1kcTZ6emUvZm9vLnRzIn0=
