Describe the bug
TaskThumbWindow disappears too soon. The user can't reach the thumbnail window because it closes instantly.

Steps to reproduce

1. Go to Cairo.xaml
2. Set CairoTaskbarButtonInactiveStyle BorderThickness to 0
3. Run the app
4. Hover the mouse over a task button try accessing TaskThumbWindow

Expected behavior
Instead of instantly closing, TaskThumbWindow should have a short grace period to account for the time it takes to move the mouse pointer from a task button to the thumbnail window.
