Makes auto-completion in application.yml consistent with application.properties. #1341
Description
Expected Behavior
In application.properties, the auto-completion is smooth when typing any words. But in yml, you need to press . or Ctrl+Space to pop up the window, which is troublesome. I want a consistent experience.
Current Behavior
application.properties
application.yml (need to press . or Ctrl+Space to pop up the window)
