Entering play mode re-centers the graph

Steps to reproduce:

1. Create and open an empty project
2. Install com.unity.behavior
3. Create and open a behavior graph (Assets > Create > Behavior > Behavior Graph)
4. Move or zoom around the graph
5. Enter play mode

Actual results: The graph gets re-centered

Expected results: The graph stays in the same position

Reproducible with versions:
1.0.7

Tested on (OS): MacOS

Notes:

• Brought up in Discussions forum here – this is a problem in large graphs because you have to re-position the graph to where you were working before after entering play mode, which is annoying
