The window icons (shown on taskbar, top-left of window, etc.) are indeed set
This is the case for normal windows applications as well. There is no
requirement that the icon associated with a shortcut and the window icon which
is actually used by an application started by that shortcut be the same.
The multiwindow mode integrated WM understands about _NET_WM_ICON  and
WM_HINTS  X window properties and hopefully converts a suitable icon found
there on the fly into a Windows icon.
It's up to the X application itself how those properties get set.
