### Describe the bug
**Info:** Investigation shows that this is related to enhanced navigation and DOM preservation. See comment.
I have a Blazor Server app with mixed render modes, SSR and WebAssembly (Auto). Some pages are server-rendered, and a couple of them have dynamic components (WebAssembly Auto) that set the title depending on content.
In ``App.razor``, I have added render mode to the ``HeadOutlet``:
```razor
```
Upon navigating to to a page, ``PageTitle`` is then only updated/rendered for the pages with dynamic components setting them, but not the server-side rendered pages.
They instead default to their address:
The `````` element is not even rendered in ``<head></head>``.
### Expected Behavior
That PageTitle works in components of all modes a in mixed render mode app.
Even if ``HeadOutlet`` has the ``@rendermode="@RenderMode.Auto"`` the ``PageTitle``of SSR pages should be rendered.
### Steps To Reproduce
1. Create a Blazor Server app.
2. Update ``App.razor``:
```razor
<HeadOutlet @rendermode="@RenderMode.Auto" />
```
3. Create a page component which has a dynamic component that declares a ``PageTitle``.
