Tasks interfering despite sequence order

[kamilmielnik]

Type: Bug

1. Create tasks.json:

Note "dependsOrder": "sequence".
Document formatter is Prettier.

{
  "version": "2.0.0",
  "tasks": [
    {
      "label": "organize-imports",
      "command": "${command:editor.action.organizeImports}"
    },
    {
      "label": "format-document",
      "command": "${command:editor.action.formatDocument}"
    },
    {
      "label": "format",
      "dependsOrder": "sequence",
      "dependsOn": ["organize-imports", "format-document"],
      "problemMatcher": []
    }
  ]
}

2. Create keybindings.json:

[
  {
    "key": "ctrl+alt+f",
    "command": "workbench.action.tasks.runTask",
    "args": "format"
  }
]

3. Create and save a TypeScript file:

import { unusedImport } from 'somewhere';

const x =         111;

4. Hit Ctrl + Alt + F

---

Expected result

const x = 111;

Actual result
It will inconsistently, randomly(?) give 2 different results (either one of 2 requested tasks)

import { unusedImport } from 'somewhere';

const x = 111;

or

const x =         111;

Notes

1. The same thing happens with extensions such as https://github.com/geddski/macros (even with the fix). I was testing it a lot.
2. I'm actually trying to run 3 tasks in sequence (also eslint.executeAutofix in between the two from example), but 2 tasks are enough to reproduce the issue.
3. Adding a delay in between the tasks helps:

{
  // See https://go.microsoft.com/fwlink/?LinkId=733558
  // for the documentation about the tasks.json format
  "version": "2.0.0",
  "tasks": [
    {
      "label": "organize-imports",
      "command": "${command:editor.action.organizeImports}"
    },
    {
      "label": "sleep-1",
      "type": "shell",
      "command": "/usr/bin/sleep",
      "args": ["0"]
    },
    {
      "label": "eslint",
      "command": "${command:eslint.executeAutofix}"
    },
    {
      "label": "sleep-2",
      "type": "shell",
      "command": "/usr/bin/sleep",
      "args": ["0"]
    },
    {
      "label": "prettier",
      "command": "${command:editor.action.formatDocument}"
    },
    {
      "label": "format",
      "dependsOrder": "sequence",
      "dependsOn": ["organize-imports", "sleep-1", "eslint", "sleep-2", "prettier"],
      "problemMatcher": []
    }
  ]
}
