How to reproduce:
1. Create and open a new project
2. Install the Behavior package
3. In the Assets folder create a Behavior Graph (Create → Behavior → Behavior Graph)
4. Open the Behavior Graph
5. Right click and create a new Custom Action node named “Test” (Add… → Action → Create new Action…)
6. Inside the newly created “TestAction.cs” script change the “TestAction” class to inherit from Composite instead of Action
7. Inside the Behavior Graph create a new Action node using the created Custom Action “Test” (Add… → Action → Test)
8. Observe the created Action nodes

Expected result: Both of the created nodes display Composite styling
Actual result: The first created Action node retains the Action styling, while the second one displays the Composite styling
