References to released media objects are not cleared

Bug Report

Problem

Within Media.js a reference to every media object is stored in the mediaObjects object. When the resources are released the reference remains. This leads to a slow memory leak when many sounds are played. In our use case there are many short sounds which we play repeatedly (sometimes releasing in between), each time a new Media instance is created (even for the same sound file) a new record is added to mediaObjects, and never removed.

What is expected to happen?

There is no memory footprint for released media objects.

What does actually happen?

A small memory footprint remains

Environment, Platform, Device
