Thanks for your quick reply.
Intercept do work, its source code:
$intercept.absolute = /[\s>+~]/;
if( selector == 'self' && target == this || $intercept.absolute.test
(selector)
? $(selector).index(target) != -1 :
$target.is(selector) )
ret = handlers[selector].apply(target,
arguments) !== false &&
ret;
It checks whether the selector is simple or complex, use $target.is
(selector) or $(selector).index.

$intercept.absolute.test(selector)
64 ? $(selector).index(target) != -1 : $target.is(selector) )
