 3. With target `ES2018`, the specific POSIX classes `[:graph:]` and `[:print:]` use ASCII-based versions rather than the Unicode versions available for target `ES2024` and later, and they result in an error if using strict `accuracy`.
 4. Target `ES2018` doesn't support nested *negated* character classes.
 5. It's not an error for *numbered* backreferences to come before their referenced group in Oniguruma, but an error is the best path for Oniguruma-To-ES because (1) most placements are mistakes and can never match (based on the Oniguruma behavior for backreferences to nonparticipating groups), (2) erroring matches the behavior of named backreferences, and (3) the edge cases where they're matchable rely on rules for backreference resetting within quantified groups that are different in JavaScript and aren't emulatable. Note that it's not a backreference in the first place if using `\10` or higher and not as many capturing groups are defined to the left (it's an octal or identity escape).
