   Javier (@javierdlg) Curious if this was an intentional design or not -- giving WM_MOUSEWHEEL support to the HWND instead of the Container will let us send "wheel events" to the connected console application 😄

   Dustin L. Howett (@DHowett) hard to say if this was intentional, that section was implemented by Zoey who sadly already left MS. If we're able to forward these to the HWND without breaking the WPF I'm okay with the change.

   On another note, are there more people using the WPF container for the terminal?
