Merge branch 'dev/migrie/b/fix-clipboard' into dev/migrie/rel/fun

this is a port of ce15032 onto main, for just the FG change.

When we cloak our window, we want to make sure to _manually_ give FG
back to another window. Because apparently cloaked windows can have FG.
beacause that makes sense 🤦

Closes #39638

 - Run tests in the Test Explorer (`Test > Test Explorer` or `Ctrl+E, T`).
 
-## Running tests in pipeline
-
-The PowerToys UI test pipeline provides flexible options for building and testing:
-
-### Pipeline Options
-
-- **useLatestOfficialBuild**: When checked, downloads the latest official PowerToys build and installs it for testing. This skips the full solution build and only builds UI test projects.
-
-- **useCurrentBranchBuild**: When checked along with `useLatestOfficialBuild`, downloads the official build from the current branch instead of main.
-
-  **Default value**: `false` (downloads from main branch)
-  
-  **When to use this**:
-  - **Default scenario**: The pipeline tests against the latest signed PowerToys build from the `main` branch, regardless of which branch your test code changes are from
-  - **Custom branch testing**: Only specify `true` when:
-    - Your branch has produced its own signed PowerToys build via the official build pipeline
-    - You want to test against that specific branch's PowerToys build instead of main
-    - You are testing PowerToys functionality changes that are only available in your branch's build
-  
-  **Important notes**:
-  - The test pipeline itself runs from your specified branch, but by default tests against the main branch's PowerToys build
-  - Not all branches have signed builds available - only use this if you're certain your branch has a signed build
-  - If enabled but no build exists for your branch, the pipeline may fail or fall back to main
-
-- **uiTestModules**: Specify which UI test modules to build and run. This parameter controls both the `.csproj` projects to build and the `.dll` test assemblies to execute. Examples:
-  - `['UITests-FancyZones']` - Only FancyZones UI tests
-  - `['MouseUtils.UITests']` - Only MouseUtils UI tests
-  - `['UITests-FancyZones', 'MouseUtils.UITests']` - Multiple specific modules
-  - Leave empty to build and run all UI test modules
-
-  **Important**: The `uiTestModules` parameter values must match both the test project names (for `.csproj` selection during build) and the test assembly names (for `.dll` execution during testing).
-
-### Build Modes
-
-1. **Official Build + Selective Testing** (`useLatestOfficialBuild = true`)
-   - Downloads and installs official PowerToys build
-   - Builds only specified UI test projects
-   - Runs specified UI tests against installed PowerToys
-   - Controlled by `uiTestModules` parameter
-
-2. **Full Build + Testing** (`useLatestOfficialBuild = false`)
-   - Builds entire PowerToys solution
-   - Builds UI test projects (all or specific based on `uiTestModules`)
-   - Runs UI tests (all or specific based on `uiTestModules`)
-   - Uses freshly built PowerToys for testing
-
-> **Note**: Both modes support the `uiTestModules` parameter to control which specific UI test modules to build and run.
