1267207 - html5 audio duration is kept after the src attribute has been removed

Status: UNCONFIRMED

(Core :: Audio/Video: Playback, defect, P3)

Description

[Tig]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0
Build ID: 20160309193552

Steps to reproduce:

In HTML / Javascript:

HTML:
<audio id="audioPlayer"></audio>
<a href="#" onclick="clearTrack();return false">clear track</a>

Javascript:
var a = document.getElementById('audioPlayer');
a.src = '/path/to/valid/file.mp3';
a.play();

function clearTrack() {
    a.pause();
    a.currentTime = 0;
    // Setting duration to 0 does nothing too
    //a.duration = 0;
    a.removeAttribute("src");
    console.log('src:['+ a.src +'] duration:['+ a.duration +']');
}


Actual results:

Track will play. Clicking "clear track" will stop the audio and the console log will show no 'src' value (correct) but will show a 'duration' of the track, which no longer exists.


Expected results:

'duration' should also be removed or reset to zero or null or false or undefined when the src attribute is removed.

Reproduced on latest Nightly. A link showing the issue: http://jsbin.com/digituguga/edit?html,js,output.

Another thing that worth to be noticed is that other browsers, like Chrome, have the same behavior. I won't mark this as new because I don't know if this is the expected behavior or not. Maybe someone else can confirm.
