[Bug]: "Clear" / "Reload" button in CodeSandbox does not reset user edits to original sample code

Summary

Component: Interactive Code Sandbox

Steps to Reproduce:

1. Navigate to the "Treat state as read-only" section in the React documentation.
2. Modify the sample code inside the sandbox. Change:

position.x = e.clientX;
position.y = e.clientY;

to:

const p = { x: e.clientX, y: e.clientY };
setPosition(p);

3.Observe that the red dot starts following the cursor as expected.
4.Click the "Clear" or "Reload" button on the sandbox to undo the edits and restore the original code sample.

Expected Result:
The sandbox should revert to the original, unedited sample code (position.x = e.clientX), and the red dot should stop following the cursor.

Actual Result:
The red dot continues to follow the cursor despite triggering a reset.

Empieza reproduciendo el comportamiento de restablecimiento en la sección "Treat state as read-only" de react.dev/learn/updating-objects-in-state y, después, sigue el flujo de restablecimiento de Interactive Code Sandbox. Se considera terminado cuando Clear o Reload restaura el código de ejemplo original y el punto rojo deja de seguir al cursor.
