In bug 829093 we called window.alert twice but only one of them is displayed.

I know I ran into this issue as well, but I recall this happening with more than just alert. What about other prompts?
Unclear why this should block -- can you provide more info about concrete user impact?

I'm not able to reproduce it, do you have an STR?

I tested it by patching dialer and opening it:
diff --git a/apps/communications/dialer/js/dialer.js b/apps/communications/dialer/js/dialer.js
index e897468..5d52eb6 100644
--- a/apps/communications/dialer/js/dialer.js

 'use strict';
 
+setTimeout(function () {
+  alert('First');
+  alert('Second');
+});
+
 var CallHandler = (function callHandler() {
   var callScreenWindow = null;
   var callScreenWindowLoaded = false;

Alert repro

Apply this patch and follow the STR:

 1. Open settings -> Bluetooth
 2. Pair with a device
 3. Deny it from the other device
 4. Wait

You will found two log message "==== errorMessage ..." in logcat but only one alert window is ever showed.

One of them is from a DOMRequest onerror callback and the other one is from a system message handler callback.

I cannot reproduce this by using setTimeout nor addEventListener on visibilitychange either.

bb? because of potential message lose.
