<pre>This is a bug with the Media Source Extensions and background tabs in Safari.
When attaching a new MediaSource to an Audio element source while the tab is in the background, the 'sourceopen' is never triggered.
Repro here: <a href="http://jsbin.com/hecohedugo/edit?js,console">http://jsbin.com/hecohedugo/edit?js,console</a>
Actual behavior:
- When a MediaSource is attached to an Audio src while the tab is in the background, the readyState is closed until the user focuses on the tab.
Expected behavior:
- When a MediaSource is attached to an Audio src while the tab is in the background, the readyState should be open.</pre>
