Currently, you have these content types :

• A with default workflow name first
• B with no default workflow name
• C with no default workflow name, C extends A and B
• D with default workflow name second
• E with no default workflow name, E extends C and D

Currently, on getting the default workflow name, we have :

• A : first
• B : content
• C : content
• D : second
• E : content

But we should have :

• A : first
• B : content
• C : first
• D : second
• E : undefined

I don't think there is some complicated cases like this currently, but it could happen in the future.
