Platform channel memory leak on macOS embedder
Steps to reproduce
We are using the binary messenger directly with our own codec, not that that should make a difference. I will dig into this some more, but it looks like the memory allocated by SendPlatformMessage() which is owned by a MallocMapping() is not freed.
Expected results
No leaked memory.
Actual results
Leaked memory.
Code sample
This is a report from the leaks tool.
