Allocator.Temp not reporting leak

I'm noticing that doing the following on the main thread or in a job and then not ever disposing of it does not create a reported leak (where as TempJob does).

NativeList<byte> b = new NativeList<byte>(16, Allocator.Temp);

Is Allocator.Temp allocated memory getting automatically cleaned up somewhere? Or is it just not reporting?

 

I think it may be cleaned automatically.

Awesome, thanks!
