Compatibility issue with Cinnamon 4.4.x and Groupped Window List

I'm using Arch Linux with Cinnamon 4.4.x and the applet Grouped Window List. Recently I started using gis-weather as well and at first everything seemed to be OK - until I put the computer to sleep (I don't shut it down).

Any program that was open and running BEFORE I put the computer to sleep, becomes unclickable after I wake it up. For instance, the programs I used most every single day are PCManFM and Firefox and therefore I rarely close them. Before I put the computer to sleep I usually minimize both of them. But after waking up none of their icons is clickable and therefore I can't maximize them.

The described problems can only be fixed by 2 ways: either by closing gis-weather (right click on it, choose "Close") or rebooting the computer. These problems happen only AFTER waking the computer up. They don't happen after rebooting. I was using both widget and tray icon of gis-weather. I'm mentioning that bc I think it may be relevant. Here's my system decription in case you need it:
