This is not NOTREACHED - it is reachable, e.g. by an incorrect use from the
plugin, but also if DidDestroyPlugin and SimulateInputEvent messages cross each
other when out-of-process.
In general, if we have an error return value, we'd return PP_ERROR_FAILED or
something. If we don't really care here, you can simply DLOG.
