Describe the bug

When applying the 'key ordering' quickfix to make the keys in alphabetical order, certain parts of the YAML get broken.

Here is an example case:

one:
  child: moo
two:
  child: moo
three:
  child: moo

Apply the quickfix to order two after three

Expected Behavior

When the quickfix is applied, the resulting YAML represents the same data. I am expecting the resulting YAML to look like this:

one:
  child: moo
two:
  child: moo
three:
  child: moo

Current Behavior

one:
  child: moo
three:
  child: mootwo:
  child: moo

Steps to Reproduce

1. Enable key ordering errors, eg. "yaml.keyOrdering": true,
2. Make the above example YAML
3. Apply the quickfix
