Null Reference Exception in UI elements when switching VFX graph
Repro:
- download attached project
- keep the VFX Editor docked as is in the project
- open the Portal VFX graph
- switch to scene view
- then go to the UnityLogog folder and open the UnityLogo VFX graph
- notice the console getting spammed by these errors:
NullReferenceException: Object reference not set to an instance of an object

Note: this issue MAY affect 2019.1 and 2019.2, but because of this bug: https://fogbugz.unity3d.com/f/cases/1116430 i cannot verify this. I will check once this other issue gets fixed!
