The mouse position is not updated when the "Mouse.WarpCursorPosition" function is executed
How to reproduce:
1. Open the “WarpMousePosition.zip“ project
2. Open the “SampleScene”
3. Enter Play Mode
4. Click the Left mouse button anywhere on the Game view
5. Observe the mouse moving to the center-opposite side of the Game view and the Console logging the from-to positions
6. Click the Left mouse without having moved the mouse in the Game view
7. Observe the Game view and Console
Expected results: The mouse changes position in the Game view and flipped coordinates are logged in the Console
Actual results: The mouse does not change position and the Console logs the same coordinates on every click
Reproducible in: 1.6.3; 1.8.1 (2021.3.40f1, 2022.3.37f1), 1.8.2 (2021.3.40f1, 2022.3.37f1, 6000.0.10f1)

Since it requires a mouse, Windows and MacOS are most of the scenarios. I guess you could test WebGL and Linux as well. This needs to be fixed. It looks really ugly and I have not found a work around short of rewriting major chunks of Unity including their EventSystem.
Why isn't MacOS keeping up?

I kept the hardware mouse visible and strangely, it does move. The problem is no one acknowledges the move until you go to move the mouse. Any movement of the mouse updates everything to the warped to spot.
If I were to guess without ever seeing the code, the WarpCursorPosition() routine just needs to set the Mouse.current.delta Vector2 and that would fix it. Or set a flag that the mouse has moved and check the flag when testing the delta.
Regardless, this should be a small fix and it is really ugly on the Mac. My Windows code runs beautifully.
