--- Comment #4 from Karl Dubost <karlcow at apple.com> ---
not sure the failures on activeCues are due to onloadeddata

Most of the subtests are passing there 
http://wpt.live/html/semantics/embedded-content/media-elements/interfaces/TextTrack/activeCues.html

For example the first test failing in Safari is

TextTrack.activeCues, empty list

For Safari
assert_not_equals(null, null, "t2.activeCues should not be null")
 /html/semantics/embedded-content/media-elements/interfaces/TextTrack/activeCues.html:32:22

For Firefox 
assert_not_equals(object "[object TextTrackCueList]", null, "t2.activeCues should not be null")
 /html/semantics/embedded-content/media-elements/interfaces/TextTrack/acti

And onloadeddata is called but this is on a VideoElement. 

This probably needs a different test.

HTMLElement interface defines an .onloadeddata property

Let's see 
https://html.spec.whatwg.org/multipage/dom.html#htmlelement


It's defined in the Global
https://html.spec.whatwg.org/multipage/webappapis.html#event-handlers-on-elements,-document-objects,-and-window-objects
> The following are the event handlers (and their corresponding event handler event types) that must be supported by all HTML elements, as both event handler content attributes and event handler IDL attributes; and that must be supported by all Document and Window objects, as event handler IDL attributes:

> The following events fire on media elements as part of the processing model described above:


In JSHTMLElement.cpp

{ "onloadeddata"_s, JSC::PropertyAttribute::CustomAccessor | JSC::PropertyAttribute::DOMAttribute, NoIntrinsic, { HashTableValue::GetterSetterType, jsHTMLElement_onloadeddata, setJSHTMLElement_onloadeddata } },
