[Shortcut Guide] Improve Desktop Preview when using multiple displays

[boop5]

When using the Shortcut-Guide only the active window will be shown in preview. But all displays will be available in the preview area.

Environment

Windows build number: Microsoft Windows [Version 10.0.18363.900]
PowerToys version: Release v0.18.2
PowerToy module for which you are reporting the bug (if applicable): Shortcut Guide

Steps to reproduce

Open the Shortcut Guide

Expected behavior

Not sure. There are 2 possible behaviors in my opinion.

a) Show the desktop in the preview area just like it is
b) Only show the active window but hide the display previews

The current behavior

c) Display all available displays as black squares in the preview area but only show the active window

Actual behavior

When bringing up the Shortcut Guide it displays all avilable displays as "black boxes" but only shows the active window - if one is selected.
