What happened to yaml editing in 2018?

There seems to be some very different behavior's wrt to yaml in 2018. For example

given

- name: Check for foobar
  fail: msg="..."
  when: check == true

With the cursor at the 'n' in name, hit return, I would expect the result to be

- 
  name: Check for foobar
  fail: msg="..."
  when: check == true

But instead it is this with the cursor still just before the 'n' in name

  name: Check for foobar
  fail: msg="..."
  when: check == true

Super annoying. Is this a bug or some new assumption on syntax?
