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`.
