(Of course I haven't ruled out everything just by finding one usage - it's
only from jquery if it happens to be from jquery. I'm assuming that is
the case most or all of the time, since the expression is nice and
obscure.)

I just discovered that this is intentional. It is called from an assert()
routine in some versions of jquery:
// This should fail with an exception
// Gecko does not error, returns false instead
matches.call( div, "[s!='']:x" );
So that's something that looks on the surface like an error but we don't have
to try to fix it.
