-e: I am using a List<byte[]> to store incoming binary messages. The code breaks when exported to WebGL. Often, a message that was stored in the list gets a length of 0 bytes, even though the original had some data.

-repro:
--create new project
--add attached ListOfByteArrays.cs to scene
--run in editor
--notice the logs in console
--build development build for WebGL and run
--NOTICE the very different list logs

--workaround as per user comment: initializing list for total needed length
