Js file in Qml module does not respect import namespace

while importing module like

import MyModule 1.0 as Lol

Qml components are available only by Lol namespace. But javascript files are available with namespace prefix and without it.

Thus bug shows up when I defined my custom Math.js file, and tried to import it within namespace.
Then any reference to global Math functions results with

TypeError: Property 'any_Math_function' of object [object Object] is not a function
