Outlet in root route prevents suspense from bubbling up

Describe the bug

I would like to use my own loading component at the root level. To do that I'm wrapping the <Outlet> in the root component with a <Suspense> block. Unfortunately, Outlet wraps the children in a <Suspense> block of its own, preventing mine from being used. Since I have no defaultPendingComponent configured, it renders nothing.

I have traced the issue to this part of the code: https://github.com/TanStack/router/blob/f7c74bc2d9fb8a587d300482e1d658a021792439/packages/react-router/src/Match.tsx#L294-L302
