Describe the bug

The pendingComponent is not displayed when the route is in a pending state (through the loader method)

Steps to Reproduce the Bug or Issue

1. clone the repo
2. run npm install
3. run npm run dev

Expected behavior

The pendingComponent is expected to be displayed in the "/" route for 2 seconds (the duration of the awaited promise in loader), however, the browser is in a pending state and the first response from the server is after the loader has finished

this is working as expected. the loader will block the server response. if you dont want this, use deferred loading or even better, stream the data using useSuspenseQuery.
