On actions that cause a component to remount (e.g. changing a value of a hook inside the component), the `devtools` source field disappears.

React version: 18.2.0

## Steps To Reproduce

1. Clone this repo: https://github.com/idango10/fiber-debug-source-issue (simple project made with `create-react-app`, only difference is `src/App.js` and `src/Comp.js`.
2. Open `devtools` -> `Components`, and navigate to the `Comp`.
3. Verify that the source field exists.
4. Change the value of the hook (e.g. from `'initial value'` to `'new value'`) and save the file.
5. Go back to the browser. and navigate back to the `Comp` in `devtools`.
6. You'll see that the source field vanished.

## Code example:

Let's say I have two components:

```js
export function InnerComp() {
    const [value] = React.useState('initial value');

    return <span>{value}</span>;
}
```

```js
import { InnerComp } from './InnerComp';

function OuterComp() {
    return <InnerComp />;
}
```

Looking at `Comp` in `devtools` -> `Components`, we'll see that there's a source field. 
If I change `'initial value'` to `'new value'` inside `useState` of `InnerComp`:
```js
export function InnerComp() {
    const [value] = React.useState('new value');

    return <span>{value}</span>;
}
```

The source field of `Comp` will vanish.

## The current behavior
The `devtools` source field of a component vanishes after remount.

## The expected behavior
The field should stay visible.
