Specifically;
- `beacon`, `ping`, and `websocket` cannot be redirected;
- it's ok to not specify a type when redirecting to `empty`
resource;
- `csp=` option can't be mixed with other types, redirec
directives, and more `csp=` options.
To be used to validate the static filtering parser code in
uBO. Over time I expect that all theparsing will be done
by the static filtering parser, and thus the list here will
become useful to detect breaking code changes.

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.
As per feedback from filter list maintainers, the
whitelist approach has been deemed to confusing.
The scriptlet has been renamed `no-setTimeout-if`
alias `nostif` to reflect the blacklist approach.
`setInterval-if` has been Similarly changed to
`no-setInterval-if` alias `nosiif`.
