• Component: Media
• Status: NEW

Hi Team,

I didn't manage to find the bug for failing 'muted.html' WPT test case, so I thought to just create it and fix these:

WPT Test Case: https://wpt.fyi/results/html/semantics/embedded-content/media-elements/user-interface/muted.html?label=master&label=experimental&aligned

WPT Live Test Case: http://wpt.live/html/semantics/embedded-content/media-elements/user-interface/muted.html

Failing test cases:

getting audio.muted with muted="" (script-created)
setting audio.muted with muted="" (script-created)

and

getting video.muted with muted="" (script-created)
setting video.muted with muted="" (script-created)

_______

Just wanted to raise for tracking.

Thanks!

In HTMLMediaElement::attributeChanged, I tried adding:

 case AttributeNames::mutedAttr:
        if (attributeModificationReason == AttributeModificationReason::Parser)
            m_muted = true;
        return;

But it didn't work.

If I change to m_explicitlyMuted = true; then it progress these four but also fail 12 more. :-(
