[V3] React plugin generates warnings for arrow function components when using jsxRuntime: "classic"

[davidwallacejackson]

Describe the bug

I'm defining a React component as an arrow function, e.g. const App = () => {...}.

This produces no warning in v2. In v3 beta 6, every arrow function component generates a warning along the lines of:

[vite] warning: Top-level "this" will be replaced with undefined since this file is an ECMAScript module
12 |  
13 |    const [count, setCount] = useState(0);
14 |    return <div className="App" __self={this} __source={{
   |                                        ^
15 |      fileName: _jsxFileName,
16 |      lineNumber: 10,
