tauri: [bug] NextJS app directory using router.push from next/navigation doesn't render page correctly.

Describe the bug

I was uncertain whether to open this in Tauri or NextJS, so I opened issues in both platforms.

While utilizing a NextJS application, version 13, and the experimental app directory, I encountered an issue where using router.push to navigate to a new page fails to render correctly. Although the navigation occurs successfully, the page only displays code as text instead of rendering the expected content. I have not found any console logs or errors related to this issue.

This problem only arises after building and running the application. Locally, everything seems to be functioning correctly. See video:

Reproduction

1. Ran npx create-next-app@latest --experimental-app

2. Set up Tauri

   2.1: Ran pnpm add -D @tauri-apps/cli

   2.2: Added tauri to package.json scripts. Ran pnpm tauri init.

3. Updated next.config.js to use output: "export" for SSG (Static Generation).

4. Made a simple page at app/examplePage/page.tsx

5. Imported next/navigation in app/page.tsx and added a button that calls router.push('/examplePage').

6. Ran pnpm tauri dev and clicked the button. The app navigated to the example page as expected and rendered it properly.

7. Ran pnpm tauri build and opened the app. Clicked the button. The app did naviate to the example page, but it did not render it properly. The page rendered code as text instead of rendering the page.

Expected behavior

The page should render correctly like it does in dev.
