Hi Alive and Dominic,

Because of Bug 1167465, we need to do this work around[1] here,
or the bug will block our works.

My only question is what if you missing the first-paint event because you are lazily loaded...?

r+ if this fixes the problem but would like to see followup to address the missing event.

This can't possibly right. We can't land a patch with this behavior.

Evan,

As we discussed offline, "system-first-paint" event looks a workable but probably not a suitable timing, I think there is a reason to explain why it works but the other events, let's investigate this together after you got back.

Discussed with Alive and Dominic in person.We could try to use "Broadcast Channel API" to get the String list of System's audio channels. Let's try that!

The documentations of Broadcast Channel API:

Broadcast Channel API cannot work for this situation. Then I'll try Fabrice's suggestion[1].

If the CI[1] for pr[2] is good, just land the code.
