           Summary: Naver Line tray icon is always gray since 9.13
           Product: Wine
           Version: 9.13
          Hardware: x86-64
                OS: Linux

Since Wine 9.13, Naver Line always shows a gray tray icon. In older wine, it
shows a gray icon if the user is not logged in yet, a green icon after logging
in, and an icon with a red "N" symbol if there are unread messages - probably
there are more different icons.

git bisect points to

I have no idea how the change is related to the tray icon, though. Also, I
cannot test if reverting that commit brings back correct tray icons, as
building fails with:

../wine/dlls/win32u/window.c:1868:25: error: ‘is_layered’ undeclared (first use
in this function); did you mean ‘ulw_layered’?

Steps to reproduce:
1. Download and install Naver Line following steps in
https://bugs.winehq.org/show_bug.cgi?id=56999
2. Create an account and log in

P.S. I tried to add the author of the the aforementioned commit. Sorry if I did
it wrong!
