Describe the bug
When sharing a window, the mouse pointer is included in the shared screen video stream, even if another window is on top of the shared window in the Z order. It seems that the system should realize that the mouse is no longer active in the shared window and then not include it in the shared screen video stream.

To Reproduce
Steps to reproduce the behavior:

1. Get into a call with user A and B.
2. User A shares a window
3. User A overlaps the shared window with a second window
4. User A moves the mouse in the second window, within the area that is overlapping the shared window
5. Notice on User B's side that the shared screen video stream is still showing the mouse pointer.

Expected behavior
It is expected that when the mouse is within the second (overlapping) window, it would not be included in the shared screen video stream. It is misleading.
