Blazor Web App (InteractiveWebAssembly): Page title flashes to domain name during hydration

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Describe the bug

In a newly created Blazor Web App using the `InteractiveWebAssembly` render mode, the page title briefly flashes to the domain name (e.g., `localhost:port`) during the hydration phase when the WebAssembly app takes over from the server pre-rendered HTML.

Because the browser falls back to the domain name when a `` tag is missing, it appears there is a gap during the `<HeadOutlet>` handoff where the title is completely removed before being re-injected by the WASM client.

This is an issue because it causes web crawlers to save the domain name as page title, affecting SEO. The bigger the page, the more time the hydration process takes, and the more chances Google gets the wrong page title.

### Expected Behavior

The page title defined in `<PageTitle>` should remain persistent during the handoff from server pre-rendering to WebAssembly interactive mode without flashing.

### Steps To Reproduce

- Create a brand new Blazor Web App
- Version: **.NET 10.0**
- Interactive render mode: **WebAssembly**
- Interactivity location: **Global**
- Include sample page
- Run the project
- Refresh the page
- Notice the page title flashing very fast (but not so fast when the page is bigger)
