Saving CMS Page Title from REST web API makes content empty

[adarshkhatri]

I am not sure if this is a bug or feature. I am trying to update the CMS Page title from POSTMAN. It updates title but also makes content and other fields empty.

Preconditions (*)

1. At least 1 CMS page
2. Web API auth key

Steps to reproduce (*)

1. Go to the postman and use this URL and body content with PUT method
   URL: http://www.example.com/rest/all/V1/cmsPage/ID (replace ID with your id (integer)
   Body:

{"page":
	{
		"title": "My Title"
	}
}

Expected result (*)

1. Update TITLE and keep all other fields same/unchanged
2. OR only update the field provided.

Actual result (*)

1. Updates title and makes all other fields (not provided in the body) null.

How do I update title only or content only? I want to update one field only (title at this stage).
