Ran across this bug in the editor.
When validating it should not consider this valid json:
There should be an error due to the fact that there is no comma between "baz" and "bim"
Sadly, there is a bug in the outline window that displays valid JSON as an error. The outline is trying to be a bit too clever when displaying the outline for invalid JSON.
I'll look to revert the outline parser so that it fails invalid JSON only.
