Misplaced transitions when using composite states

[ghost]

stateDiagram-v2
	[*] --> A
  state A {
    B1 --> B2
  }	
  A --> C: s
  C --> D			
  B1 --> D
  A --> D: aaaaaaaaaaaaaaaa

renders as

• the description "s" for the A --> C transition and the transition arrow is misplaced
• the description for the A --> D transition is misplaced, note that increasing the description length exacerbates the placement of the A --> C transition (looks like x and y is wrongly swapped in code)
