Setting muted attribute on <video> element is not reflected in controls
https://bugs.webkit.org/show_bug.cgi?id=127726
Reviewed by Eric Carlson.
Source/WebCore:
If the 'muted' IDL attribute is queried after the 'muted' and 'src' content attributes are
set but before loading begins, it will return 'false' until loading begins, but with no
way to query whether that value is valid, nor firing a volumechange event when its value
changes.
The HTML spec says that the 'muted' content attribute controls whether audio output is
muted "when the media element is created", not when loading begins, but we don't
necessarily have a signal that the element is fully parsed. Additionally, this means its
impossible to make an element via script and get this behavior.
So the new behavior is that the 'muted' IDL attribute will always reflect the 'muted'
content attribute up until one of the following three conditions:
- The 'muted' IDL attribute is set via script.
- The element is inserted in the document.
- The element begins loading.
After the first one of the above conditions, the 'muted' IDL attribute will no longer
change when the 'muted' content attribute changes.
