SUMMARY
Web Apps added from Chromium based browsers doesn't show its own icon.
The expected behaviours is that each installed app has its own icon in taskbar, but regular browser windows should still group. 

STEPS TO REPRODUCE
1. Open a chromium based broswer, like Chromium, Edge or Google Chrome
2. Open a web app like Gmail
3. Add it as an app 
4. New window opens

OBSERVED RESULT
Its icon in taskbar is grouped within the main browser window icon despite having a different WM_CLASS string added by the browser

EXPECTED RESULT
Web Apps should have its own icon in taskbar.
