Description Matthew Gregan [:kinetik] 2013-06-24 02:15:57 UTC 
This would maintain the invariant that element.videoPlaybackQuality === element.videoPlaybackQuality.

Or if a new object is absolutely required each time, videoPlaybackQuality should be changed from an attribute to a method.

This attribute is mimicking HTMLMediaElement.buffered, seekable, and played attributes where a new object is returned on every fetch. This is to make sure that all the values in the object stay consistent with eachother since values are intended to be compared with one another.
Comment 2 Boris Zbarsky 2013-06-26 05:36:52 UTC 
Why are we mimicking terrible APIs?

If you want to return a new object each time, use a method, not an attribute.  Abusing attributes like this is really bad from the point of view of JS API consumers...

Change committed.
