jQuery delegated events are not propagated to show the "events" icon in the INSPECTOR view.

[TheLaGmAn]

I also submited a bug here (dont know if its the correct place)

https://bugzilla.mozilla.org/show_bug.cgi?id=1270884

Steps to reproduce:

HTML:
<script src="https://code.jquery.com/jquery-2.2.3.js" integrity="sha256-laXWtGydpwqJ8JA+X9x2miwmaiKhn8tVmOVEigRNtP4=" crossorigin="anonymous"></script>
<style> .media_preview { width:100px; height:100px; display:inline-block; margin:10px; } </style>
`

` `<script> $(document).ready(function(){ $(".media_preview_container").on("click.test",".media_preview",function(){ alert('clicked on media preview class'); }); }); </script>`

Steps:
Open dev console, browse the .media_preview DIV and it has no event icon set, only the .media_preview_container has it and it doesnt point to any child, so there is no way to know that event is actually delegated to .media_preview

Actual results:

.media_preview doesnt show an event icon even tho it has an event assigned thru a delegation of .media_preview_container

Expected results:

Show the event icon in the .media_preview DIV and show its event code.
