Hi Petr,
MS Windows always sends WHEEL events to the focused window. And my
testing shows that when you scroll the wheel outside of an AWT window,
the scroll events are consumed (by AWT, supposedly).
With your fix you seem to always redirect the events to the window under
the mouse. Now suppose you have a 3rd-party window with a scroll bar in
background (e.g. Windows Explorer). If an AWT window is currently
focused, but you move the mouse pointer outside of it and above the
Explorer window, and start scrolling, will the Explorer window scroll
its contents? Currently it doesn't. What about if we apply your fix?

Hello, AWT Team.
Please review the fix for the issue:
https://bugs.openjdk.java.net/browse/JDK-8025585
The fix is available at:
http://cr.openjdk.java.net/~pchelko/8025585/webrev.00/
The fix is needed for JFXPanel support. We need to redispatch MOUSEWHEEL
messages to the window under mouse. In case of Popups in a JFXPanel the HWND
belongs to a different tollkit, so we need to use ::SendMessage to redispatch
the message.
With best regards. Petr.
