Nested Dependent tasks are run multiple times

[OldStarchy]

I'd like to reopen this issue #43076 as it's basically the same thing except that my task setup is slightly different.

My abridged tasks.json

{
	"tasks": [
		{
			"label": "dev",
			"dependsOn": ["yarn watch", "yarn dev"],
			"isBackground": true
		},
		{
			"label": "yarn watch",
			"dependsOn": ["start container"],
			"isBackground": true
		},
		{
			"label": "yarn dev",
			"dependsOn": ["start container"],
			"isBackground": true
		},
		{
			"label": "start container",
		}
	]
}

Starting "dev" causes "start server" to start twice, they conflict with each other, and then both fail.

My workarounds are

1. Remove the "dependsOn" property from "yarn dev". This way I can run "dev", wait for the watch to start, then run "dev" again. No different to manually starting the server before running "dev" though.
2. Globally install "concurrently" and merge the two watch tasks into one.

I don't have a root-level package.json (or equivalent) for this project.

Same root cause as #118238, except this one has a work around:

{
	"tasks": [
		{
			"label": "_dev",
			"dependsOn": ["yarn watch", "yarn dev"],
			"isBackground": true
		},
		{
			"label": "dev",
			"dependsOn": ["start container", "_dev"],
			"dependsOrder": "sequence",
			"isBackground": true
		},
		{
			"label": "yarn watch",
			"isBackground": true
		},
		{
			"label": "yarn dev",
			"isBackground": true
		},
		{
			"label": "start container",
		}
	]
}
