Volume slider appears/doesn't appear at the wrong times

2 things here:
a) set pointer-events: none of background divs for volume slider so the box doesn't appear randomly
b) call drawVolumeBackground on the over event for the mute box.

Note that the slider drew for <video> elements before because we drew it as a result of calling showControls().

However, we don't call showControls() for <audio> elements because the controls are always visible anyways.

I'm not sure why you needed to do this. As long as the backgrounds are behind the controls, wouldn't the control get the event?

In this situation, when the volume box is hidden, the controls have a width of 0, so the background, while hidden, are above the controls.

Maybe a better way to do this is to make the widths of the background divs 0 as well while hidden.
