Fix inactive window passes events to window below (#4561, #4835)

Prior to this fix, if all of the following conditions were met: + While a modal window (such as the Preferences dialog) was open. + 'Multiple window UI' was enabled. + A non-modal window (such as the Preview window) overlapped the modal window. + The non-modal window was selected, so this window is on top of the modal window. Caused mouse clicks and movements within the overlay area of ​​the non-modal window to be incorrectly passed to the window below, i.e. the modal window. Instead, it would be expected that no action would be taken. @dacap note: At the moment this fix only works on macOS because the os::WindowSpec::modal() parameter is only used on macOS.
