    window-list: Update icon on app changes
    
    We currently assume that the application associated with a particular
    window is fixed. While this holds true for almost every application,
    there are some cases of multi-app-packages like LibreOffice where
    windows may change the properties used for application matching at
    runtime. Catch those cases to make sure we display the correct icon
    when the window shifts applications.
