Redirecting to a static page with a revalidation time after entering draft mode shows stale content

### Link to the code that reproduces this issue https://codesandbox.io/p/devbox/next-draft-mode-with-revalidate-bug-9p7dtw ### To Reproduce 1. Start the application in production (`pnpm build && pnpm start`) 2. Open Chrome devtools. Ensure caching is not disabled. Go to the cookies section in the Application tab. 3. Toggle on draft mode by pressing the toggle button. - Observe that the beside text now says "enabled" and the `__prerender_bypass` cookie was set. 4. Toggle off draft mode by pressing the toggle button again. - Observe that the beside text now say "disabled" and the `__prerender_bypass` cookie is gone. 5. Toggle on draft mode again by pressing the toggle button. - Observe that the beside text still says "disabled", however the `__prerender_bypass` cookie was set. - Observe also that the second to last RSC request uses disk cache, rather than fetching fresh. ### Current vs. Expected behavior Current behavior: - Redirecting to a page with a custom [`revalidate` config](https://nextjs.org/docs/app/api-reference/file-conventions/route-segment-config#revalidate) time causes stale content to show after entering draft mode. - In other words, it seems like Next isn't properly busting the cache before redirecting after entering draft mode if the RSC response has a `stale-while-revalidate` in its Cache-Control header. - It also seems like redirecting from a server function is erroneously performing a redundant navigation from the client. https://github.com/user-attachments/assets/a69250f5-1f6b-4211-b8d0-b9a49ad08e95 | Server Action Response | Redundant Navigation Response | | ------------- | ------------- | | <img width="1059" height="314" alt="Image" src="https://github.com/user-attachments/assets/7360ccb1-c9da-4867-aca0-3fc9092d5531" /> | <img width="1059" height="314" alt="Image" src="https://github.com/user-attachments/assets/acdb060a-8b11-4bf7-ba62-2624f3991107" /> | Expected behavior: - Entering draft mode and redirecting should bust/sk…
