:is(selector):upward(selector) works very slowly #136

Related to - https://github.com/AdguardTeam/AdguardFilters/issues/97686

Steps to reproduce

  1. Add this rule: 
    euro.com.pl#?#body > :is(a):upward(test)
  2. Go to - https://www.euro.com.pl/telefony-komorkowe.bhtml

Website is loading very slowly due to rule from first point.

If I understand correctly, "running" such rules takes a lot of time, but I think it shouldn't.
