Does it work on browser or not?

# Bug Report

## Problem
The readme states that the supported platforms includes the Browser, but I can't get it to play on the browser.

The cordova warning appears in the console and nothing happens... am I doing something wrong?
`common.js:297 Native: tried accessing the Media plugin but Cordova is not available. Make sure to include cordova.js or run in a device/simulator`

## Checklist

- [x] I searched for existing GitHub issues
- [X] I updated all Cordova tooling to most recent version

Start by comparing the Browser support claim in the README with the behavior reported at common.js:297, then reproduce the warning in a browser using the current Cordova tooling. Determine whether browser playback is supported; done means the plugin behavior or the documented platform support clearly matches the verified result.
