A few comments on the 'position: absolute-anchored':

 (1) The interaction with CSS transforms is different from the

 (Elements with a CSS transform establish a containing block for
 position:fixed elements.)  If it is intentional, are implementors
 really ok with that (given the desire to be able to do things like
 animate transforms on another thread, and interactions with things
 like z-ordering rules)?

 specifiable in CSS; it breaks basic ideas of round-tripping and the

 (3) Is there a way to get notified when new CSS features are added
 to the HTML spec?  I only happened to stumble across this one.
