Give a warning when the root load function failed.

Describe the problem

Currently, the code in

kit/packages/kit/src/runtime/client/client.js

Line 903 in 7c8dbf3

return await server_fallback(url, { id: route.id }, error, status);

does not give a warning after form submission when an error is thrown in the load (using the kit version throw error(500, error)) but just refreshes the whole page and omits the error. It would be nice if the error was shown to be able to debug the application.

Describe the proposed solution

Add a log statement that is visible in dev and prints error.

By the nature of the solution (reloading the page) there isn't really a good place to print an error, since it will immediately vanish when the page reloads. I'm not sure what the right fix is — perhaps adding a debugger statement to prevent the reload?

Thanks a lot!
