P: Scripting: JavaScript app.batch method ignores specified Action Set

Scenario: Create set "Set1", then another set "Set2". Record different actions in both of sets but use the same name for the action "MyAction". When you run Application.batch command via code - Photoshop always run "MyAction" from the first set (Set1) regardles if code requested to pick action from Set2.
In Documentation of PhotoShop JavaScript reference for Application.batch() it is written that it expects 4 arguments: batch(inputFiles, action, from [, options]). The "from" argument is set to "Set2" but script always run  "MyAction" from the first available set having the action labeled as requested in action argument ("Set1" int that case). InputFiles and optional options are set properly and they works as expected, the only problem is the inability to control the parent set if batch is ran via code.

Is this fixable?
Thank you.
