Description Chris Dumez 2020-08-13 16:34:28 PDT

Make sure OfflineAudioContext::startOfflineRendering() does lazy initialization before actually starting rendering. If lazy initialization has not happened yet (because no audio nodes were created for this context yet), then rendering would fail with an InvalidStateError, due to lack on initialization.
