Title: Volume slider doesn't set initial height properly

The volume slider must be visible when its height and position is set, but `secondTry` isn't detected due to the wrong operator being used in a boolean statement:

```javascript
if (!volumeSlider.is(':visible') && typeof secondTry != 'undefined') {
volumeSlider.show();
positionVolumeHandle(volume, true);
volumeSlider.hide()
return;
}
```

In the above code, it should check to see if `typeof secondTry === 'undefined'`.
