[HybridWebView] InvokeDotNet not triggered on .NET 10 projects (works on .NET 9)

Nobody has claimed this yet.

### Description

In a .NET MAUI app using HybridWebView, JavaScript → .NET invocation (via InvokeDotNet) does not trigger on .NET 10 projects. The same codebase works correctly on .NET 9. This breaks JS-to-.NET messaging from the embedded web content.

Note: I’ve attached net 10.0 minimal reproduction repo and a short screen capture demonstrating the behavior.

### Steps to Reproduce

[HybridWebViewNet10.zip](https://github.com/user-attachments/files/25334412/HybridWebViewNet10.zip)
1. Download the attached sample and open the solution.
2. Restore & build both projects (Net9 and Net10).
3. In the web view, click the “InvokeDotNet” button that triggers InvokeDotNet method from JS.
4. Observe:
.NET 9 project → .NET callback receives the payload and updates the UI/log.
.NET 10 project → No callback received (no UI/log updates).

### Version with bug

10.0.40

### Is this a regression from previous behavior?

Not sure, did not test other versions

### Last version that worked well

9.0.0 GA

### Affected platforms

I was *not* able test on other platforms

### Affected platform versions

_No response_

### Did you find any workaround?

_No response_

### Relevant log output

```shell

```

Start with the attached HybridWebViewNet10.zip reproduction, restore and build both the .NET 9 and .NET 10 projects, then click the InvokeDotNet button in the web view. Compare the working .NET 9 callback with the missing .NET 10 callback. Done means JavaScript invokes .NET and the callback receives the payload and updates the UI or log in the .NET 10 project.
