Progressive web app integration with wayland is not working correctly.
STEPS TO REPRODUCE
1. Install a Browser that supports own window (no browser menus) window progressive web apps (PWA). Chromium-Browser, Brave-Browser, Google-Chrome, Microsoft-Edge.
2. Open a web page that has support for running as a Progressive web app. Say Spotify or SoundCloud.
3. Add the PWA launcher to the OS using the browsers method for this. Most Chromium based browsers have this feature called "add shortcut" in the "more tools" sub menu. When clicking it you must check the open as window shortcut.
4. Now you launcher menu should have an icon/launcher that can start the PWA as an web application in its own window. Attach this launcher to the taskbar
On kwin X11 this window will tie it self to the launcher of the PWA in the taskbar.
On kwin wayland this window will tie itself to the browser launcher in the taskbar.
On kwin wayland this window should tie it self to the launcher of the PWA in the taskbar.

Similar to 358277 but this is only in wayland. X11 works fine.

This will be fixed in Plasma 5.25
Well, I'm using 5.25.2 and the issue still persists.
I'm on Plasma 5.25.5, but the issue is still there.

Have you try to set chrome://flags/#ozone-platform-hint to "wayland" ?
I already switched to X11.
But thanks for the hint!

This fixed it for me, quite similar in brave: setting brave://flags/#ozone-platform-hint to "Auto" or "Wayland". It comes configured with "Default" which at this point in time equals "X11"
