NetworkManager Transport Serializefield Broken in 2020.1.4f1

[LukeStampfli]

Describe the bug
When using MLAPI with 2020.1.4f1 the NetworkTransport field manager resets to None when entering playmode in the editor. After leaving playmode the serialize field still shows as Null.

This issue does not happen on 2020.2.0f1, 2021.1.0f1

To Reproduce
Steps to reproduce the behavior:

1. Create a new project using Unity 2020.1.4f1
2. Follow the installation guide to install MLAPI.
3. Add a NetworkManger to your scene. Assign a UNetTransport to the NetworkTransport field
4. Enter playmode, before pressing StartHost/Server/Client see how the NetworkTransport field is None.
5. Leave playmode the field still stays as None

Expected behavior
NetworkTransport should not be set to None like it other Unity versions.

Screenshots
before enter play mode:

after enter play mode:

Environment (please complete the following information):

• Windows 10

Just a detail, in item 3 I believe it's s not Networktransform, it's NetworkTransport

Right, should've been NetworkTransport, thanks.

The team had some questions about this. Perhaps you can setup a sync

This only occurs in one particular Editor version.
Closing after confirming with Luke.
