      Root Cause

      https://github.com/zkoss/zk/blob/v8.6.0/zk/src/archive/web/js/zk/au.js#L1221

      Workaround

      patch the redirect function to keep the au requests enabled:

      zk.afterMount(function() {
	var redirectOrig = zAu.cmd0.redirect;
	zAu.cmd0.redirect = function() {
		redirectOrig.apply(this, arguments);
		if(zk.confirmClose && zAu.disabledRequest) {
			zAu.disabledRequest = false;
		}
	}
});
