Window-Snap via keyboard shortcut has no effect on cmd.exe but it works on mouse dragging

Window-Snap does work properly when dragging cmd.exe to left-screen border via mouse
Window-Snap does not work properly when WinKey-left is used on cmd.exe
0.4.12-RC-52-g3fa352b__cmd_WinkeyLeft_fails.webm

The misbehavior of the keyboard-shortcut is specific to cmd.exe, e.g. it works as expected for the file-browser-window.

ros logs nothing, therefore I skipped the logfile

Expected result
Win7_ok.webm
Noteworthy is, that Win7 does never use all available vertical space, neither on WinKey-left, nor on WinKey-up, nor on Win-Key-right. Eventually it tries to enlarge in multiple of cmd-font-height. I would accept also a fix as 'complete', that would not dive that much into the details yet.
