Description of the new feature/enhancement

Focus follows mouse allows one to direct input into the exposed terminal tab while another window is selected so long as the mouse pointer is positioned anywhere over the Windows Terminal window.

This will reduce extra mouse clicks and make switching input focus more streamlined.

Proposed technical implementation details (optional)

Given that another window is selected and active, focus follows mouse allows one to direct input into the exposed terminal tab when the mouse pointer is positioned anywhere over the Windows Terminal window. One does not have to click on the Windows Terminal window to active input focus.
