Summary: Fixes T2146. This is a really simple approach, you just do: !print .rule { whatever: blah; } And it transforms it into: .printable .rule { whatever: blah; } @media print { .rule { whatever: blah; } } So we end up with these rules twice, but they should compress well and we shouldn't need that many of them, and this fix is way way simpler than all the nonsense I discussed in T2146. Test Plan: - Added a unit test. - Added a simple rule to throw away the menubar when printing. - Checked the latter with `/?__print__=1`.
