Describe the bug

In CommunityToolkit/WindowsCommunityToolkit#4092 we moved to WinUI 2.6.1 and our InfiniteCanvas control uses a InkToolbarCustomToggleButton for enabling drawing with the mouse. After updating to WinUI 2.6.1, when that button is clicked it does not show it in the pressed state, but it does behave normally otherwise.

Steps to reproduce the bug

Steps to reproduce the behavior:

1. Checkout the branch for Update all relevant WinUI 2.5 revs to 2.6 CommunityToolkit/WindowsCommunityToolkit#4092
2. Open the project in visual studio
3. Build and Run Microsoft.Toolkit.Uwp.SampleApp in the project.
4. Search for and open the "InfiniteCanvas" sample in the sample app at the top right corner.
5. Click the "Hand Button".
6. See it now visually change into a clear pressed state.

Expected behavior

When the "Hand Button" it clicked its visual representation changes to show it is in a pressed state.
