Cinnamon ignores application request to restore the window from minimized state

[whimboo]

 * Cinnamon version - (4.0.9)
 * Distribution - (Mint 19.1)
 * Graphics hardware - (Intel 3rd Gen Core processor Graphics Controller [rev 9])
 * Graphics driver - (no proprietary driver installed)
 * 64 bit

Issue
Cinnamon ignores application requests to restore a minimized window. Manually clicking on the panel button works, and restores the window. Also switching to a different window manager like MATE solves the problem for me.

Steps to reproduce
To reproduce the issue please use the following steps by using Firefox:

1. Start Firefox
2. Press F12 to open the developer tools and press F1 to open the settings
3. Activate Enable browser chrome and add-on debugging toolboxes
4. Press Shift+F4 to open the Scratchpad editor
5. Add the code: window.restore();
6. Select Environment -> Browser
7. Minimize the browser window
8. Go back to the Scratchpad and press Ctrl+R to execute the script

Expected behaviour
Running the script has to restore the minimized browser window.
