Bug 2000520 [wpt PR 56045] - TaskAttribution: Propagate through EventTarget::EnqueueEvent(), a=testonly
Automatic update from web-platform-tests
TaskAttribution: Propagate through EventTarget::EnqueueEvent()
EventTarget::EnqueueEvent() is used for some events to dispatch the
event asynchronously in a new task. This can be used during API calls,
e.g. HTMLMediaElement.addTextTrack(), or from misc spec algorithms, e.g.
queuing the hashchange event during a same-document navigation -- which
is a case that needs to be instrumented to support soft navigation
detection. In either case, we should propagate the current context to
match causal/disptach propagation semantics.
