Which project does this relate to?

Router

Describe the bug

@tanstack/solid-router does not properly transition manual Suspense boundaries. I find that only the route boundaries get held up in a transition, while manual Suspense boundaries always show fallback on navigation.

Your Example Website or App

https://github.com/jakst/tss-suspense-transition

Steps to Reproduce the Bug or Issue

1. Clone repo, pnpm install, start dev server, open page
2. Click the button to increase the query param n
3. Observe that Suspense fallback always triggers

Expected behavior

I expect suspense boundaries to transition (i.e., hold the old value instead of falling back) on navigation.
