NoResize window shrinks when moving to different DPI monitor with Shift+Win+Arrow

Copied from VSO ID: 823555

* Does the bug reproduce also in WPF for .NET Framework 4.8?: Yes

**Steps to reproduce:**

1. Set up two monitors, one with 100% DPI and one with 200% DPI.
2. Create a WPF app whose main window has ResizeMode=NoResize and WindowStyle=None
3. Start the app on the 200% monitor
4. Move the window to the 100% monitor using the Shift+Win+Arrow shortcut. If necessary, move it back and forth between the monitors a few times that way.

Result: the window shrinks (in logical dimensions). If there is content, the content will be clipped.

I think this is the root cause of the issue below:
