So according to the lastet comments adding a StartupWMClass
corresponding to the name of the application's executable to each Wine
.desktop file would be a temporary workaround for this problem, until
it's fixed in Wine? Let's try it:

find "$HOME/.local/share/applications/wine/Programs" -name '*.desktop'
-exec perl -pi -e 'if (m/^Exec=.+ \/Unix (.+\.lnk)/) { ($l = $1) =~
s/\\\\ / /g; $r = qx[env WINEDEBUG=-all wine shortcut /f:"$l" /a:q]; if
($r =~ m/\nTargetPath=(?:.+\\)?([^\\\n]+)/) { print
"StartupWMClass=$1\n"; } }' '{}' \;

And hey, it works! Mostly, that is, for me. A few exceptions turned out
to be due to to EITHER differences in capitalization between what's in
the .lnk file and the actual exectutable on disk OR some internal
shenanigans by program loaders/cracks.

Try this workarond at your own risk. Be sure to backup
~/.local/share/applications/wine/Programs beforehand. You may have to
run "xdg-desktop-menu forceupdate" to see any changes. YMMV. To revert
the changes, i.e. to remove all StartupWMClass lines from all Wine
.desktop files:

find "$HOME/.local/share/applications/wine/Programs" -name '*.desktop'
-exec perl -pi -e 's/StartupWMClass=.+\n//' '{}' \;

This workaround (or a permanent fix) also seems to fix

Bug description:
  If I start an application using Crossover (or Wine), the application will always be the Wine Logo instead of the application logo. This is the same independent of the application being run or using Wine instead of Crossover.
  That makes sense if the application has no logo, but it gets confusing running multiple Microsoft Office programs - and all of them have the same logo.
  The hint text for the icon is also "Wine Windows Program Loader" instead of "Document 1 - Microsoft Word" as it should be.
  Unity does not seem to allow Wine/Crossover to use application icons and title text.

  I have confirmed that this issue does NOT occur in Gnome Classic, and
  is only a Unity flaw.
