Not possible to focus to a new activated window while being focused outside of VM (Hyper-V)

### Describe the bug

When testing my app in Hyper-V, if I switch focus outside of Hyper-V and a new window activates in the meantime, I’m unable to focus on the new window and click the button.

### Screenshots

_No response_

### NuGet package version

Windows App SDK 1.6.1: 1.6.240923002

### Packaging type

Unpackaged

### Windows version

Windows 11 version 22H2 (22621, 2022 Update)

### IDE

Visual Studio 2022

### Additional context

If I click at the window and then I press any key, it starts working again. **Looks like it's related to 1.6, I'm not able to replicate it with "1.5.240607001" and "10.0.26100.1" version.**

Start by running the provided FocusBug.zip reproduction in Hyper-V with Windows App SDK 1.6.1, then compare its focus behavior with the listed 1.5 and 10.0.26100.1 versions. No source file or test is named; done means identifying the regression and restoring the ability to focus and click the newly activated window while focus is outside the VM.
