1077046 - implement MediaSource.prototype.isTypeSupported

Status: RESOLVED INVALID

(Core :: Audio/Video, defect)

Description

[(not reading bugmail) Nick Desaulniers [:\n]]

From the spec [0].  I noticed that when I tried to pass 'audio/mp3' to MediaSource.prototype.addSourceBuffer I got an error [1].  When I tried to check if that type was supported, I got an error.

```javascript
(new MediaSource).isTypeSupported('audio/mp3');
```

Use MediaSource.isTypeSupported() as it is declared static.
