Settings writer looses comments

Have a setting defined that is an array of literal (an example is the tasks.json with the tasks property). Try to update the array using the settings API with comments used for elements inside the array or on elements in the array.

Observe: comments are lost

tasks.json

{
	// See https://go.microsoft.com/fwlink/?LinkId=733558
	// for the documentation about the tasks.json format
	"version": "2.0.0",
	"tasks": [
		{
			// a comment
			"type": "gulp",
			"task": "build",
			"problemMatcher": [
				"$tsc"
			]
		}
	]
}

configure a second task using the configuration UI (the gear icon in the task quick open). You get:

{
	// See https://go.microsoft.com/fwlink/?LinkId=733558
	// for the documentation about the tasks.json format
	"version": "2.0.0",
	"tasks": [
		{
			"type": "gulp",
			"task": "build",
			"problemMatcher": [
				"$tsc"
			]
		},
		{
			"type": "gulp",
			"task": "watch",
			"problemMatcher": []
		}
	]
}

I couldn’t find a way to preserve the comment.

@sandy081 Loosing comments is a “user data loss” that we must avoid. We need to fix this.

Any progress on this issue?
