The contents of Map Magic's (latest version) editor panel are not shown in Peek's maximised mode, or at least get destroyed and/or not redrawn.
Steps to repro:
1. add MapMagic game object to scene
2. click Show Editor in the MapMagic component to bring up its editor panel, you can see its graph
3. hit play and the contents of the MM editor panel disappear and selecting the MM gameobject in the scene does not repopulate it (like it would it non-maximised/normal editor mode)
