// jose 6.2.12's error classes (dist/webapi/util/errors.js), verbatim in
// shape: minifiers join a derived constructor's statements into one comma
// expression that opens with super(...). Each comma operand runs as its
// own statement, so the base constructor and the class field initializers
// finish before the trailing assignments.
