<Suspense /> when navigating via <Link /> not working

In my page i have this server component:
        <Suspense fallback={<Loading />}>
          <Table mapPromise={mapPromise} />
        </Suspense>

<Table /> is an async component that takes very long to load. So if i navigate to the page via its url i don't see the <Table /> i see the <Loading /> until <Table /> is ready. But if i navigate via a <Link />
like:
   <LinkDefault
       href={`/abas/articlecompare?old=${oldValue}&new=${newValue}`}
       prefetch={false}
     >
            Open
     </LinkDefault>

The Browser does not show my <Loading /> component. It just does nothing, the url does not change until the <Table /> is loaded. Then the url changes and i see the <Table />.
I want to see the normal <Suspense /> fallback value when i navigate to an url via a <Link />.
Is this not intended like this? Am i doing something wrong?

I can't share my current code. If i find time i will do a repro repo.
However i found a solution by adding a key to the suspense https://github.com/vercel/next.js/discussions/50563

This is driving me crazy.
Not even the loading.tsx is showing in this case.
It seems the only solution is to make the page a client component and simply fetch the data while handling the state yourself.
However, this makes server components pretty much useless for pages with dynamic data.

most likely you used suspense wrong

It's not just the <Suspense /> tho.
I can remove it and get the same issue.
I have a page. That page server-component has a child, which is an async server-component. This child takes a few minutes to load.
So if i open the url to my page i would next.js expect to show my loading.js instead of the page until my child is loaded.
This works.
But if i navigate to the same page via a <Link /> component it does not work. I don't see the loading.js and the browser is just unresponsive till the page (including the async child) has loaded.

I will maybe try later to come up with a reproduction repo.

yes, to re-trigger Suspense again you need to add keys
