Description of the problem

It looks like there are a few problems at play here:

1. If Sandpack times out while loading and the error overlay is displayed, there's no way for the user to know that Sandpack is disconnected. As a result any further changes that the user makes will not cause the preview to update with the new changes
2. The "restart" sandpack button doesn't work. If the loading times out and the Sandpack disconnects, triggering a restart just causes a blank screen.

Steps to reproduce:

1. Create a Sandpack in such a way that there's a compilation error before the first load
2. Wait for Sandpack loading time out (~45 seconds)
3. Move/Hide the error overlay (don't remove it from the DOM otherwise it will cause a different error)
4. Click "restart sandpack"
5. Observe the broken state
