Tray icon for steam is missing in wine 9.7.

I did bisecting and found that it's started with following commit:

b5c57b9a62c396068d18237bd6e82b37c169fdc5 is the first bad commit

explorer: Set layered style on systray icons only when it's actually
layered.

Fixes a regression introduced by 229b4561d9a8f10cbb49342dff0b6a3472d81c68,
    which caused the icons to not be visible initially in the virtual desktop
    systray.
