What steps will reproduce the problem?


Here is the code: (cl/119970475)

PopupBlockerCheckController.prototype.validatePopUpBlocker = function() {
  // Open the smallest window possible.
  let popupWindow = goog.window.open('about:blank', {
    target: 'popupTest',
    width: 0,
    height: 0,
    top: 0,
    left: 0,
    toolbar: false,
    location: false,
    statusbar: false,
    menubar: false
  });
  if (!popupWindow || popupWindow.closed) {
    // popup blocked
    this.runningMessage_.setStyle('display', 'none');
    this.failedMessage_.setStyle('display', 'block');
    this.passedMessage_.setStyle('display', 'none');
  } else {
    // popup opened
    popupWindow.close();
    this.runningMessage_.setStyle('display', 'none');
    this.failedMessage_.setStyle('display', 'none');
    this.passedMessage_.setStyle('display', 'block');
  }
};

We have this code to test if the popup blocker is on, and inform our user that they need to turn it of for this ads review tool (because we pop up ad landing pages).

(0) Popup blocker is on
(1) When this code trigger for the first time, this works great.
(2) Then our failed message show up. 
(3) I clicked a button to trigger this code a second time.
(4) The popup blocked did not block the popup, and the test passed. (I put a break point and confirmed that the popup come up.

What is the expected result?
No matter how many times this is fired, it should continue blocking popup.


What happens instead?
I defeated the popup blocker.
