Bug description

System Settings > Keyboard > Shortcuts > Windows group: setting a hotkey for "Toggle shaded state" works only to shade the window, not to unshade it.

It doesn't work at all for me if the title bar is missing from the target window (due to Cinnimon-Maximus extension), but I suppose this is by design...

Steps to reproduce

1. set a shortcut for "Toggle Window Shade"
2. highlight a window (that has a title bar).
3. press the shortcut. Window is reduced to a shade -- title bar only
4. press shortcut again. Nothing happens
5. To remove the shade if no other window action is specified, you must right-click and select some other function. (for me, I've set title bar double click to toggle maximize vertically, so that's how it unshades for me)

Expected behavior

click once, window is shaded
highlight or activate the shaded window or place cursor on shaded window, press hotkey, and window unshades

Additional information

Start by reproducing the issue through System Settings > Keyboard > Shortcuts > Windows using a window with a title bar. Trace the Toggle shaded state shortcut from that entry point and compare the first press with the second; done means the same shortcut shades and then unshades the active window, including the reported repeated-use case.
