*** New procedural cosmetic operator: `:remove()` Related issue: - https://github.com/gorhill/uBlock/issues/2252 The purpose is to outright remove elements from the DOM tree. Since `:remove()` is an "action" operator, it must only be used as a trailing operator (just like the `:style()` operator). AdGuard's cosmetic filter syntax `{ remove: true; }` will be converted to uBO's `:remove()` operator internally. *** New procedural cosmetic operator: `:upward(...)` The purpose is to lookup an ancestor element. When used with an integer argument, it is synonym of `:nth-ancestor()`, which will be deprecated and which will no longer be supported once no longer used in mainstream filter lists. Filter lists maintainers must only use `:upward(int)` instead of `:nth-ancestor(int)` once the new operator become available in all stable releases of uBO. `:upward()` can also accept a CSS selector as argument, in which case the nearest ancestor which matches the CSS selector will be selected.
