1427346 - The type of return value of tabs.move() is different from Google Chrome

Status: NEW

(WebExtensions :: General, defect, P5)

Description

Attachment: test-firefox.js

Steps to reproduce:

  * Run the attached test case with "tabs" permission.
    For example, open a debug window for "Tree Style Tab" extension (which has the permission) then paste the code.

Expected:

  tabs.move() is expected to return a signle tabs.Tab object when only one tab is moved.
  (Output the following debug message:
   testMoveSingleTabInOneWindow SUCCESS
   testMoveSingleTabInOneWindow SUCCESS)

  Rationale:
  * https://developer.mozilla.org/en-US/Add-ons/WebExtensions/API/tabs/move
    > A Promise that will be fulfilled with a tabs.Tab object or an array of tabs.Tab objects
  * Google Chrome returns a single tabs.Tab object in this case.

Actual:

  tabs.move() returns an array which contains a tabs.Tabs object.
  (Output the following debug message:
   testMoveSingleTabInOneWindow FAIL
   testMoveSingleTabInOneWindow FAIL)
  It seems that it never return a single tabs.Tabs object.
  The behavior of Firefox is different from Google Chrome.
