    // they already exist. The icons could be replaced (by a contrib module or
    // manually), so we don't want to replace the existing files. Removing the
    // files when we uninstall could also be a problem if the files are
    // referenced somewhere else. Since showing an error that it was not
    // possible to copy the files is also confusing, we silently do nothing.
