The error-boundary example code causes infinite loop

The example code to downcast an error and rethrow if necessary causes an infinite loop

```
rsx! {
ErrorBoundary {
handle_error: |error: ErrorContext| {
// Network errors need to be handled by a different error boundary!
if let Some(err) = error.error() {
return Err(e.into())
}

// Otherwise, handle this error here
rsx! {
div { "Oops, we encountered an error" }
}
},
// ...
}
}
```
