[Adwaita] Mouse-over/hover for non-focused windows
Currently Adwaita does not have any mouse-over / hover effect for most widgets that are in non-focused windows (ie. those that are not the current window). This gives the impression that any mouse-click would just raise the window, and not active the widget under the mouse. However, this is not correct. If you click on a button in a non-focused window, the window is raised and the button is clicked.
Can Adwaita be updated to provide some feedback upon mouse-over / hover in this case? Even if it is very subtle. Alternatively, perhaps the click should not be passed on and the window only raised (made active)?
