Sorry, I'm not just going to blindly apply a patch because some
TAHI tests fail.
It's possible the TAHI tests are wrong, or that the specification
elements it is testing don't make any sense these days.
Allowing all kinds of random junk in the middle of the fragment queue
leads to lots of unnecessary cpu overhead and potential bugs, and it
triggerable remotely.
