"Mouse.delta" returns zero when moving the cursor against the screen edge when using a Remote Desktop Connection on Windows

When the mouse cursor is against the edge of the screen and you are running Unity through a remote desktop session, Unity does not receive any input events from the OS. Unfortunately, this seems to be a limitation of RDP and we cannot fix it.
How to reproduce:
Open the user-attached project (InputSystem MouseDelta Bug.rar)
Open the SampleScene and enter Play Mode
Make sure that the Game view is maximized
Move the mouse cursor around and note the flickering
Move the mouse cursor against the side of the screen
Expected result: the Game view flickers indicating that the mouse delta isn’t zero
Actual result: the Game view remains black indicating that the mouse delta is zero
