I don't think PaymentRequest needs to be a ContextLifecycleObserver. Alternately
you can:

- Add [ConstructorCallWith=ScriptState].
- Make PaymentRequest hold RefPtr<ScriptState>.
- Extract the execution context with m_scriptState->executionContext().

[please use gerrit instead, 2016/03/02 00:32:53]

Done.
