Seems that this question won't be relevant for much longer!

Chromium 140 (and the latest edge beta) now use ozone-platform auto by default!

    This appears to be a years-old and still unfixed Chromium issue, but fortunately there is a workaround: All Web Apps Starting in Single Window · Issue #486 · flathub/com.microsoft.Edge 

    Quoting from the author, Evan Anderson:

    This is a known issue. Chromium uses a different WM class name when using Wayland. Instead of crx__appid, it uses execname-_appid-profileid. The workaround is to edit StartupWMClass in the application desktop files ~/.local/share/applications to read msedge-_appid-Default (assuming no second profile), where appid is the identifier that comes after crx__.
