Safari 9: inserting into a different document fires inserted

[daffl]

https://github.com/canjs/can-util/blob/master/dom/mutate/mutate-test.js#L36 is failing on Safari 9.0:

I think this is related to what you were seeing yesterday, with Safari not firing events unless it's in the DOM.

[matthewp]

This doesn't work in Safari:

<script>
(function(){
    var doc = document.implementation.createHTMLDocument('Demo');

    var div = document.createElement("div");
    div.addEventListener("inserted", function(){
        console.log("called");
    });

  doc.body.appendChild(div);

  var ev = doc.createEvent('HTMLEvents');
  ev.initEvent("inserted", true, false);
  div.dispatchEvent(ev);
})();
</script>

Nor does new Event()

Submitted this: web-platform-tests/wpt#3788

If they don't object I'll also file a bug against WebKit.

Thinking about a workaround.

[matthewp]

So what this test is really just testing is that mutate uses the DOCUMENT() getter to know which document to fire the inserted event against. I'm not sure how else to test this.

[daffl]

If it is a bug in Webkit we can probably just run the test conditionally for now?

[matthewp]

I guess we could. I'm going to wait and see what they say about the test I submitted and come back to this later.

[daffl]

I created #93 which feature detects if the test can be run so that we'll at least get everything else to pass on Safari.

Fixed by #93
