Improve `prevent-setTimeout`/`prevent-setInterval` scriptlet
Add support for range for the `delay` paramater: --- @param [delay] A value to match against the delay. Can be a single value for exact match, or a range: - `min-max`: matches if delay >= min and delay <= max - `min-`: matches if delay >= min - `-max`: matches if delay <= max No delay means to match any delay value. Prepend with `!` to reverse the match condition. --- As discussed with filter list maintainers.
