That said, I'm opposed to this change because it's incompatible not
only with existing implementations of media queries, but because
it's incompatible with existing pre-mediaqueries behavior.  The
following test:

http://dbaron.org/css/test/2008/mq-drop-whole-sequence

yields an aqua background in every browser I tested (Firefox trunk,
WinIE 7, WebKit trunk, Opera 9.26, Konqueror), whereas the spec
change in question seems to mandate that it have a yellow
background.
