Describe the issue you are experiencing

Attempting to edit via the code editor but the code gets checked on keystroke and modified immediately. Entering any character under the entities indentation removes the entire entity. Mistyping anywhere generates notifications such as "Visual editor is not supported for this configuration: Key 'amchart_type' is not expected or not supported by the visual editor. You can still edit your config in YAML." This is within the code editor, not via the visual editor.

Describe the behavior you expected

Allow editing and not modify code unless requested by user.

Steps to reproduce the issue

1. enter Statistics Graph Card Configuration
2. select show code editor
3. create new line under first entity under -entities:
4. start typing - enter multiple spaces to reach indentation
5. type any alphanumeric key
6. the previous entity will be removed and cursor will move to the top left ...
