hoxyq c4d091a1dc fix: devtools source field disappears after component remount (#27297)
## Summary

Fixes: https://github.com/facebook/react/issues/27296

On actions that cause a component to change its signature, and therefore
to remount, the `_debugSource` property of the fiber updates in delay
and causes the `devtools` source field to vanish.

This issue happens in
https://github.com/facebook/react/blob/main/packages/react-reconciler/src/ReactFiberBeginWork.js

```js
function beginWork(
  current: Fiber | null,
  workInProgress: Fiber,
  renderLanes: Lanes,
): Fiber | null {
  if (__DEV__) {
    if (workInProgress._debugNeedsRemount && current !== null) {
      // This will restart the begin phase with a new fiber.
      return remountFiber(
        current,
        workInProgress,
        createFiberFromTypeAndProps(
          workInProgress.type,
          workInProgress.key,
          workInProgress.pendingProps,
          workInProgress._debugOwner || null,
          workInProgress.mode,
          workInProgress.lanes,
        ),
      );
    }
  }

  // ...
```

`remountFiber` uses the 3rd parameter as the new fiber
(`createFiberFromTypeAndProps(...)`), but this parameter doesn’t contain
a `_debugSource`.
