notificationFx.js (default alert module) problem

I cannot understand this error. I think there would be no problem, but it causes an error.

[in my module]

this.sendNotification('SHOW_ALERT', {
   timer:10000,
   title: "test",
   message : "say something"
})

This cause run-time exception error.
DOMException: Failed to execute 'insertBefore' on 'Node': The node before which the new node is to be inserted is not a child of this node.
in
[notificationFx.js (line:91)]

90: // append to body or the element specified in options.wrapper
91: this.options.wrapper.insertBefore(this.ntf, this.options.wrapper.nextSibling);

this.options.wrapper is < body > .
this.ntf is div.ns-alert.ns-growl.ns-effect-jelly.ns-type-notice.
this.options.wrapper.nextSibling is span.gr__tooltip.

Is this notificationFx.js problem? But everybody except me uses this without a problem.
I’m testing this on Mac OSX with Chrome in node serveronly mode.

@Sean If you start with npm start dev, do you have the same problem?

@roramirez tomorrow I’ll try it.

@roramirez Thanks, with npm start dev, it works.

@Sean So, can be there a bug with using that browser. What version of Chrome is?
