   Related: when .sheet property for both <style> and <link rel=stylesheet> becomes available is unclear.

   According to #2997 (comment) CSS parsing should be observed atomic, so things will happen in this order

   1. loading completes
   2. stylesheet is parsed
   3. CSSStyleSheet object is ready (including cssRules being populated)
   4. .sheet is associated with the object
   5. document.styleSheets reflects the object
   6. load or error event is fired against its owner node

    As per #4031 (specifically #4031 (comment)) I think this issue can be closed. Everything in #696 (comment) seems to be properly specified in the way that the comment outlines, with the exception of the CSS parsing particulars, which is tracked by #2997 specifically. But the order of all the other steps, including their relation to the hand-wavy CSS rule parsing, looks right to me.

    I'll close this now, but please re-open if you think I am mistaken.
