It would be nice to have some way to attribute these events to a frame -- I
assume LocalFrame* that we use in other events would be difficult to get hold of
on the call site, but resource identifier should be available, so perhaps add it
so this activity is traceable to its causes, i.e. a network resource and the
owning frame.

I added requestId here.
But I don't know how to use this in the Timeline tab.
Is it OK?
