For problem statement, please see

For solution, please see

For CSS WG thinking that this is an HTML issue, please see
(FWIW, I think this is a CSS issue than requires an HTML attribute to
be minted.)

Please add an attribute to <link> that:
 * opts an external style sheet out of synchronous CSSOM access
 * makes the sheet not load and not defer the load event if its media
query cannot match in the UA even after zooming or invoking a print
 * makes the sheet load with low priority and not defer the load event
if its media query does not match at the time the <link> element is
inserted into the document but might match later (e.g. if it's a print
style sheet).
