Volumechange triggers twice the first time mute/unmute button is clicked.

[natemunk]

Expected Behavior

volume change event gets triggered one time when the mute/unmute button is clicked, and the volume returned should be 0 when muted, and higher than 0 when unmuted.

Actual Behavior

The first time the button is clicked the volume change event triggers twice. After that it only triggers once. The volume returned when the video is muted returns the previous volume level, when it should be returning 0 when the video is muted.

Steps to Reproduce

I've got an example that shows the behavior, it prints to the log
